Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 210–300 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with a particle size range of 210–300 μm and 99.5+% purity is a coarse-grade material engineered for superior thermal and mechanical performance in high-temperature and high-wear environments. This product features exceptional hardness (9.5 Mohs), high thermal conductivity, and chemical stability, making it a reliable material for robust ceramic applications, abrasives, and heavy-duty composite reinforcement.

With a consistent morphology and particle size distribution, this SiC powder ensures efficient packing and uniform dispersion in matrix materials. It is suitable for use in bulk-form refractory components, casting molds, wear-resistant coatings, and structural ceramic parts. The powder is environmentally safe, free from heavy metals, radioactive elements, and toxic or carcinogenic compounds.
