such as Nano-silicon ntride: Silicon nitride (Si3N4) â—†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 ***0, microhardness ****0Mpa, melting point ***0 ℃ (under pressure), thermal conductivity rate of *6.7W / (m • K), it does not dissolve in water , while is soluble in hydrofluoric acid; 3. The modulus is ****0 ~ ****0Mpa, bending strength **7MPa, Compressive strength is **0MPa (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 ***0 ℃ 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. â—†Main parameters Technique specification color purity Average particle size Crystal phase Specific surface area Zeta potential Loose loading density Nono-Si3N4 white >*9.0% *5 nm amorphous *0m2/g **1.8mV 0.*5g/cm3 â—†Storage This product should be sealed in vacuum and stored in cool and dry rooms, can not be exposure to air and be under stress.
