Si3N4 powder CAS 12033-89-5 Silicon Nitride powder structural ceramic materials

Brief Description of Silicon Nitride Si3N4 Powder

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.

Features of Silicon Nitride Si3N4 Powder

1. Silicon nitride powder high surface activity, low bulk density, UV reflectivity is more than 95% and absorption rate of infrared band is above 97%

2. Silicon nitride powder does not dissolve in water, soluble in hydrofluoric acid

3. Silicon nitride powder itself possesses lubrication.

4. Excellent properties of corrosion resistance, thermal conductivity, heat shock resistance and  abrasion resistance . Silicon nitride powder can be used in the environment below 1800 degree.

5. Good anti-division property and stable chemical composition.

6. Low thermal expansion coefficient, high thermal conductivity and strength..

7. Good oxidation resistance at high temperature
