Nano Silicon Nitride

Product Features

Silicon nitride (Si₃N₄) nanoparticles are prepared via aerosol ablation method, featuring high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, ultraviolet reflectivity above 95%, and infrared waveband absorption rate exceeding 97%. The resulting components exhibit low sintering temperature, excellent dimensional stability, high mechanical strength, and superior chemical corrosion resistance—particularly outstanding high-temperature strength with self-lubricating effects. When dispersed as fine phases in composite materials, they significantly enhance overall performance. The product itself possesses self-lubricating properties, making it suitable for application in lubricants. With high hardness and low sliding friction coefficient, silicon nitride can be used in ceramic wear-resistant composite plating on metal surfaces. Its incorporation into coatings provides wear resistance and solvent resistance. High-purity silicon nitride serves as a release agent for quartz crucibles.
