Characteristic


Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si3N4 is the most thermodynamically stable of the silicon nitrides. Hence, Si3N4 is the most commercially important of the silicon nitrides and is generally understood as what is being referred to where the term "silicon nitride" is used. It is a white, high-melting-point solid that is relatively chemically inert, being attacked by dilute HF and hot H2SO4. It is very hard (8.5 on the mohs scale). It has a high thermal stability.


Chemical formula:Si3N4

Molar mass:140.283 g·mol−1

Appearance:grey, odorless powder

Density:3.17 g/cm3

Melting point:1,900 °C (3,450 °F; 2,170 K)

Solubility in water:Insoluble

Refractive index (nD):2.016


Application


Silicon nitride is used as high grade refractory, such as si3n4-sic refractory combined with sic for blast furnace body and other parts;If combined with BN as si3n4-bn material, used for horizontal continuous casting separation ring.Si3n4-bn series horizontal continuous casting separation ring is a kind of fine structure ceramic material with uniform structure and high mechanical strength.Good resistance to impact, and will not be wetted by molten steel, in line with the continuous casting process requirements.

Used for preparation of thermal interface composite materials, photovoltaic demultifier, phosphor powder, preparation of special ceramics.
