Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 15–40 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with a particle size of 15–40 μm and 99.5+% purity offers an optimal balance between particle fineness and mechanical robustness, making it highly suitable for advanced ceramics, precision abrasives, and high-temperature industrial applications. Its sub-angular morphology and thermal stability provide superior wear resistance and chemical inertness in harsh operating environments.

This material is ideal for enhancing thermal conductivity and structural integrity in composite formulations, while its electrical insulation and hardness (9.5 Mohs) make it indispensable for semiconductors, refractories, and high-stress ceramic systems. It is also environmentally safe, non-radioactive, and free from heavy metals or carcinogens.
