Silicon Nitride powders feature:
1. The hardness of silicon nitride powders is about 9 to 9.5, Knoop hardness is about 2200, micro hardness is 32630Mpa, melting point is 1900 °C (under pressure) and thermal conductivity rate is 16.7W / (m · K).
2. With high surface activity, low bulk density, UV reflectivity is more than 95% and absorption rate of infrared band is above 97%.
3.Does not dissolve in water, soluble in hydrofluoric acid.
4.Nano silicon nitride modulus: 28420 ~ 46060Mpa; bending strength: 147MPa; compressive strength: 490MPa (reaction sintering). It is an important structural ceramic materials and a super-hard material.
