Product Description

Nano Silicon nitride Powder
--------EltNano-Si3N4
Characters:

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.
