Product Description
Nano Silicon nitride Powder


1. Nano-silicon nitride powder possesses high purity, small particle size distribution, high specific surface area.
2. The hardness of this product is about from 9 to 9.5, Knoop hardness about 2200, microhardness 32630Mpa, melting point 1900 (under pressure), thermal conductivity rate of 16.7W / (m · K), it does not dissolve in water, while is soluble in hydrofluoric acid;
3. The modulus is 28420 ~ 46060Mpa, bending strength 147MPa, Compressive strength is 490MPa (reaction sintering), it is an important structural ceramic materials and a super-hard material, besides it has properties of lubrication, wear resistance, corrosion resistance and high temperature oxidation. And it can withstand of heated to above 1000 in the air and then cooling rapidly. For ceramic-forming Silicon Nitride needs relative low temperature but has good dimensional stability and high mechanical strength.

This product should be sealed in vacuum and stored in cool and dry rooms, can not be exposure to air and be under stress.
