Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 300–425 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with 99.5+% purity and a particle size range of 300–425 μm is a premium-grade ceramic material engineered for high-performance applications. This coarse-size powder is particularly valuable in industries that require superior hardness, high thermal conductivity, and chemical inertness. With a Mohs hardness of 9.5 and a stable thermal expansion coefficient, it stands up to extreme conditions, making it ideal for structural and functional uses.

The material is chemically stable, non-toxic, and free of heavy metals and radioactive substances. Its consistent microstructure and mechanical strength make it suitable for demanding applications in abrasives, refractories, electronics, and high-temperature systems.
