Nano Silicon Nitride

Nano silicon nitride appears as a white solid powder, with a melting point of 1900°C (under pressure). Its thermal conductivity is 16.7 W/(m·K), and it has a low density, only 2/5 that of steel. The hardness of nano silicon nitride reaches above 9, and its compressive strength typically exceeds 1 GPa. Due to its high hardness and dense structure, it has excellent wear resistance, extending the product's lifespan.
