Tungsten Disilicide

Tungsten disilicide also known as tungsten silicide, and it is an inorganic compound, a silicide of tungsten. It is an electrically conductive ceramic material. The physical properties of tungsten disilicide are as following: chemical formula：WSi2, molar mass:240.011g/mol, density:9.3g/cm3,melting point:2160℃, which is insoluble in water, but soluble in fluorine aqua regia, what’s more, it has good anti-oxidation. Besides, there are tungsten disilicaide chermistry which is it can react violently with substances such as strong acids, fluorine, oxidizers and interhalogens.
On one hand it is used in microelectronics as a contact material, with resistively 60-80μΩcm. On the other hand it is often used as a shunt over polysilicom lines to increase their conductivity and increase signal speed.
