Bismuth Tungstate Cobalt Tungstate Composite Photocatalyst

Bismuth tungstate is a new type of visible light catalyst. Its band gap is small, its absorption light is strong and easy to be modified. Co3O4 and Bi2WO6 are combined into a composite photocatalys...

Tungsten Oxide Composite Electrode

The discharge rate performance of the two electrode materials of tungsten oxide composite electrode and tungsten oxide electrode can be obtained by subjecting the material to multiple charge-discha...

Ammonium Metatungstate Applied for Honeycomb Ceramic Catalyst

Ammonium metatungstate is used as the active component in the preparation of honeycomb ceramic catalyst. And the prepared high specific surface area porous honeycomb ceramic catalyst is particularl...

Tungsten Oxide Photocatalyst Loaded with Titanium Dioxide and Copper Ions

Titanium dioxide is known as a photocatalyst material, but it has little function in the absence of ultraviolet radiation. Therefore, Scientists prefer to study visible-light tungsten trioxide phot...

Effect of EDM on Tungsten Carbide Dies

With the continuous improvement of the specialized production degree of electronic, computer, instrument, motor and household appliances, the requirements for the life and precision of the die have...

Influence of Impurity Elements on Tungsten Alloys Properties

Impurity elements in tungsten alloys include H, O, C, N, P, S, and Si. Because these elements have small atomic radii, and strong diffusivity in alloys, they are more likely to be in the grain boun...

Phosphotungstate Simple Synthesis

Heteropoly acids are metal oxygen clusters formed by bridging metal atoms with oxygen atoms. Heteropoly acid has good catalytic performance and is an efficient bifunctional catalyst. It has not onl...

Viscous Flow of Tungsten Carbide

The sintering process of tungsten carbide is actually a process of material migration. During the sintering process, the amount and quality of particles on the bonding surface and the spheroidizati...

Tungsten Recycling from Low Grade Scheelite Tailings

At present, the content of WO3 in white tungsten flotation tailings in many mines has reached more than 0.2%, even as high as 0.4%. These tailings are very low in floatability due to strong inhibit...

Silicon Carbide／tungsten Carbide Composite Coating

Wear has become one of the main reasons for the failure of modern industrial machinery parts. With the development of industry, more and more high wear-resistant materials are required, and wear-re...
