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 A_xWO₃, 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.

The traditional narrow band gap semiconductor is usually used as photosensitive material in infrared detectors. In order to improve the detection sensitivity, shorten the response time of devices and reduce the influence of background noise, the normal operation of these devices requires liquid nitrogen refrigeration environment, which greatly limits the application and working time of devices.

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.

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.
