Cesium tungsten bronze is a blue-black powder, functional compound of non-stoichiometry and specific structure of oxygen octahedral, and has low resistivity and low temperature superconductivity property.
Tungsten trioxide, also known as tungsten oxide or tungstic anhydride, WO3, is a chemical compound containing oxygen and the transition metal tungsten.
Tungsten carbide powder (WC) is the main raw material for producing cemented carbide, chemical formula WC. Tungsten carbide powder is a black six square crystal with metallic luster and hardness similar to diamond. It is a good conductor of electricity and heat.
Tungsten belongs to the rare element in the earth's crust containing only 0.007% of China's tungsten reserves of about 55% of the world's total reserves in the first place.
