Tungsten disilicate, also known as tungsten silicate, is an inorganic silicide.
Tungsten disilicate is a black - gray (blue - black) tetragonal crystal.
Chinese name: tungsten disilicate
The foreign name: Tungsten Disilicide
Molecular formula: WSi2 Points the child quantity: 240.01
The density: 9.4(g/mL,25℃) melting points(ºC) :2165
Solubleness: insoluble in water CAS: 12039-88-2 MDL: MFCD00049704
Physical and chemical properties:Physical properties are as follows: chemical molecular formula: WSi2, melting point: 2165℃, density: 9.3g·cm3, melting point: 2160℃ (3920 °F, 2,430K), has good oxidation resistance, soluble in aqua fluoride, but insoluble in water. The chemical properties of tungsten disilicate are shown as follows: it can react violently with many substances, such as strong acids, fluorine, oxidants and interhalogen compounds.
Application Field:WSi2 is often used in microelectronics as electric shock material, including resistance is 60-80 mu Ω cm. It is also often used as a shunt on a polysilicon wire to increase its conductivity and signal speed.
