How Many Do You Know About Molybdenum Trioxde(MoO3)?





Molybdenum trioxide is chemical compound with the formula MoO3. This compound is produced on the largest scale of any molybdenum compound. It occurs as the rare mineral molybdite. Its chief application is as an oxidation catalyst and as a raw material for the production of molybdenum metal. The oxidation state of molybdenum in this compound is +6.

MoO3
Molybdenum trioxide can been used in the following:

Molybdenum trioxide is used to manufacture molybdenum metal, which serves as an additive to steel and corrosion-resistant alloys. The relevant conversion entails treatment of MoO3 with hydrogen at elevated temperatures:


MoO3 + 3 H2 Mo + 3 H2O


It is also a component of the co-catalyst used in the industrial production of acrylonitrile by the oxidation of propene andammonia.


Because of its layered structure and the ease of the Mo(VI)/Mo(V) coupling, MoO3 is of interest in electrochemical devices and displays. Molybdenum trioxide has also been suggested as a potential anti-microbial agent, e.g., in polymers. In contact with water, it forms H+ ions that can kill bacteria effectively. However, the issue of keeping the catalyst clean in an environment that would exploit such antimicrobial properties has not been explored.

SiC Heating Element

 

There are many shapes in SiC heating elements. The following is two kinds for your reference:Ther Type HY-L and HY-H 


These types of heating elements are used in applications ranging in temperature from 600°C up to 1600°C in both air and controlled atmosphere. The type of atmosphere used will determine the maximum recommended element temperature. Silicon carbide elements may be mounted either vertically or horizontally, and as the material remains rigid, even at the maximum operating temperatures, no special supports are required.
 

HY-H Type SiC Rod


Type HY-DB
 

This type of heating element consists of a hot zone with high electrical resistivity and rigidly connected with two thickened cold zones of low resistance owing to their larger diameter and special manufacturing technique. The particular connecting technique ensures perfect mechanical and electrical operation. Hot zones and cold zones are made of exceptionally homogeneous, self-bonded silicon carbide. The heating elements are self-supporting and can be installed vertically or horizontally.

HY-DB Type SiC Rod    
If you have any inquiry regarding to heating element, such as MoSi2 rod, SiC rod, pleae feel free to contatc us. Chinatungsten can provide these products for you with best service

Molybdenum Carbide Sputtering Target

Chinatungsten specializes in producing high purity Molybdenum Carbide Sputtering Targets with the highest possible density and smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. 

Our standard Sputtering Targets for thin film are available monoblock or bonded with dimensions and configurations up to 820 mm with hole drill locations and threading, beveling, grooves and backing designed to work with both older sputtering devices as well as the latest process equipment, such as large area coating for solar energy or fuel cells and flip-chip applications.

Molybdenum Sputtering Target With ≥99.95% Purity
Research sized targets are also produced as well as custom sizes and alloys. All targets areanalyzed using best demonstrated techniques including X-Ray Fluorescence (XRF), Glow Discharge Mass Spectrometry (GDMS), and Inductively Coupled Plasma (ICP). "Sputtering" allows for thin film deposition of an ultra high purity sputtering metallic or oxide material onto another solid substrate by the controlled removal and conversion of the target material into a directed gaseous/plasma phase through ionic bombardment. We can also provide targets outside this range in addition to just about any size rectangular, annular, or oval target. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. 

Chinatungsten specializes in producing custom compositions for commercial and research applications and for new proprietary technologies.  We also casts any of the rare earth metals and most other advanced materials into rod, bar or plate form, as well as other machined shapes and through other processes such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We also produce Molybdenum as disc, granules, ingot, pellets, pieces, powder, and rod. Other shapes are available by request.

Tungsten Alloy In Yacht


Waha~ It is long time no see, everybody! How is everything going with you ?  I am busy working  in my alibaba, and Hanns who is my boss is busy having his yacht training, that sounds so cool and great! And you?

Here, let me talk about yacht.

What is yacht?

A yacht is a recreational boat or ship. The term originated from the Dutch Jacht meaning "hunt". It was originally defined as a light fast sailing vessel used by the Dutch navy to pursue pirates and other transgressors around and into the shallow waters of the Low Countries. After its selection by Charles II of England as the vessel to carry him to Britain from Holland for his restoration, it came to be used to mean a vessel used to convey important persons.

Tungsten alloy is one important material in yacht. It just like the role in golf club head.

Tungsten Alloy in Yacht
A golf club head comprise one or more balance weights for swing smoothness. The balance weight is selected from a number of balance weights and placed in a weight cavity formed in the golf club head. Tungsten alloy is now widely recognized as the material for this significant role. Correctly applied tungsten alloy weight perfectly balances the club providing better overall control.

Tungsten Alloy Screw For Golf

Because of their unique properties, tungsten alloy screw is well suited for use as weights in variety of sport equipment. Tungsten heavy alloys have a density twice that of steel and weigh seven times more than aluminum.Tungsten alloy inserts allow manufacturers to locate gravity center of the ball in the perfect spot. This process has lead to improved launch, spin and forgiveness. Recent innovations have also increased the usage of tungsten in the sport. Some claim that because tungsten is dense and the center of gravity more centrally located, a tungsten alloy screw will create more spin in golf balls.

Numerous techniques have been used for weighting golf club heads in order to gain better performance. In persimmon wood club heads, weights were attached to the sole in order to lower the center of gravity. The first metal woods had sufficient weight, however, the weight distribution deterred slightly from performance.

The refinement of hollow metal woods with weighting on the sole improved upon the performance of these clubs. We use a tungsten golf screw in the sole of each titanium club head body to vary the weight of the golf club head.

Chinatungsten Online offers tungsten alloy counterweights for a variety of applications, including but not limited to various kinds of parts and tungsten alloy screw for golf clubs and weights for both clubs and balls.

Have a good time, dear Hanns!

Wolfram.en.alibaba.com


Yesterday, all of Chinatungsten Online colleagues were taken train on Alibaba which lasted 4 hours. It contains our tungsten, molybdenum and other related products in our http://wolfram.en.alibaba.com/. The construction of our company alibaba has great significance to company’s development.


Do know why we use Wolfram.en.alibaba.com not Tungsten.en.alibaba.com?

Haha~ Let me tell you the reason in the following:

Tungsten is one of those elements with a symbol that doesn't seem to correlate to its name, or at least its English name. The symbol 'W' comes from the name wolfram, which you will find on German and certain other periodic tables. A man named Peter Woulfe determined that tungsten was a new substance, but the element's name doesn't derive from his name. Rather, it comes from the Swedish wolf rahm, which refers to the way the ore wolframite (Fe, Mn)WO4 intereferes with tin smelting, appearing to devour the metal.

Alibaba Group is a family of Internet-based businesses which makes it easy for anyone to buy or sell online anywhere in the world. Since its inception, it has developed leading businesses in consumer e-commerce, online payment, business-to-business marketplaces and cloud computing, reaching Internet users in more than 240 countries and regions. Alibaba Group consists of 25 business units and is focused on fostering the development of an open, collaborative and prosperous e-commerce ecosystem.

We get lots of  ideas and knowledge from this Alibaba train.  And there are so many things to do, it may  be take one week, half  a month and even more time. As the saying goes that All Things Are Dificult Before 

They Are Easy.Competition always carries abreast challenges and opportunities to everyone involved and we  hope that our company can has a new development and appearance by AliBaba.

Time is money, let us fighting together, all my dear chinatungsten colleagues!

Happy Chinese Valentine’s Day To My Whole Chinatungsten Colleagues


Today is the Chinese Valentine’s Day!

My colleague Sarah who in charge of molybdenum receives a branch of red roses from her boy friend in this morning.  A total of eleven red roses  and thet means Love her whole life. They are so beautiful and their love is so sweet. So wish them happiness forever.

Means Love~
Means Love~
Here, Let us talk about  Chinese Valentine’s Day together!

On the seventh day of the seventh lunar month, raise your head and gaze at the stars, you will find something romantic going on in the sky.

VALENTINE’S Day in China, the seventh day of the seventh lunar month, falls on August 13 this year.
That is, on Monday evening, Niu Lang and Zhi Nu will meet on a bridge of magpies across the Milky Way. Chinese grannies will remind children that they would not be able to see any magpies on that evening because all the magpies have left to form a bridge in the heavens with their wings.

Romantic legend

The legend has been handed down for nearly 2 millennia. The story has been recorded as far back as the Jin Dynasty (256-420 AD). Poets composed hundreds of verses on the love story and many types of Chinese opera tell the story.

The Chinese people believe that the star Vega, east of the Milky Way, is Zhi Nu and, at the constellation of Aquila, on the western side of the Milky Way, Niu Lang waits for his wife.

Looks So Hot~
Looks So Hot~
Zhi Nu was said to be the youngest of seven daughters of the Queen of Heaven. With her sisters, she worked hard to weave beautiful clouds in the sky, while Niu Lang was a poor orphan cowherd, driven out of his home by his elder brother and his cruel wife.

Niu Lang lamented over his lonely and poor life with an old cow, his only friend and companion. The magical cow kindly told him of a way to find a beautiful and nice woman as his life companion.

Under the direction of the cow, Niu Lang went to the riverside on an evening, where the seven fairies slipped out of their heavenly palace to bathe.

He took one of the beautiful silk dresses the fairies had left on the bank. When the fairies left the water, the youngest couldn’t find her clothes and had to see her sisters fly back to heaven without her.

Then Niu Lang came out with the dress and asked the youngest fairy, Zhi Nu, to stay with him.

Several years passed on Earth, which were only a few days in heaven. Niu Lang and Zhi Nu lived happily together and had two children before the Queen of Heaven discovered Zhi Nu’s absence.

She was so annoyed she had Zhi Nu brought back to heaven. Seeing his beloved wife flying in the sky, Niu Lang was terrified. He caught sight of the cowhide hanging on a wall. The magical cow had told him before dying of old age: “Keep the cowhide for emergency use.”

Putting the cowhide on, he went after his wife with his two children.

With the help of the cowhide, Niu Lang was able to follow Zhi Nu into heaven. He was about to reach his wife when the Queen showed up and pulled off her hairpin to draw a line between the two. The line became the Silver River in heaven, or the Milky Way.

Zhi Nu went back to the heavenly workshop, going on weaving the clouds. But she was so sad, and missed her husband across the Silver River so much that the clouds she weaved seemed sad. Finally, the Queen showed a little mercy, allowing the couple to meet once every year on the Silver River.

In the evening, people sit outdoors to observe the stars. Chinese grannies would say that, if you stand under a grapevine, you can probably overhear what Zhi Nu and Niu Lang are talking about.

At last, make my  best wishes to the whole Chinatungsten colleagues( contains tungsten,molybdenum and tungsten carbide  departments) on Chinese Valentine’s Day!
