Tungsten trioxide has excellent performances in electrochromic, catalytic and gas sensitivity. Tungsten bronze, a composite oxide of tungsten bronze, generally refers to metal oxides with deep metallic luster, and is usually metal conductor or metal semiconductor. Tungsten bronze general AxWO3, however, varies with the type and molar number of cations. The structure and color of the compounds will vary with the different values of A and X.

Tungstate is a typical self-starting luminescent material. Its luminescent spectrum is very stable. Its intrinsic luminescent band is very wide and occupies most of the visible region. Cations in tungstate strongly affect the position of the emission band. Tungstates can be activated by some impurities which, when doped into tungstate lattices, can make them luminescent with special properties, such as magnesium.

Preparation Process of Tungsten-based heavy alloy core material

Tungsten-based heavy alloy core material Image

Depleted uranium composites are the most excellent penetrating core materials due to their excellent self-sharpness. In the early 1990s, based on the international public opinion and environmental pressure caused by the toxicity of depleted uranium materials, the United States began to develop an alternative uranium armor piercing core. material. On the basis of the tungsten-nickel-iron heavy alloy, the researchers designed a tungsten-based heavy alloy armor-piercing projectile through the change of the microstructure of the alloy, but there is still a big gap between the self-sharpening effect of the depleted uranium alloy.

Electrochromic means that the optical properties of materials change reversibly under the action of an applied electric field. The color and optical transmittance of electrochromic materials can be changed at low voltage, and the fading state of electrochromic materials can be maintained under open circuit condition. With this characteristic, electrochromic devices are widely used in energy saving, optical regulation and other fields. Wisdom window is one of its most representative applications.
