Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 90–125 μm

Product Description:
Our Silicon Carbide (SiC) Micron Powder with a particle size distribution of 90–125 μm and a minimum purity of 99.5% is engineered for superior thermal and mechanical performance in advanced industrial applications. Known for its exceptional hardness (9.5 Mohs) and high thermal conductivity, this powder is particularly well-suited for use in high-temperature environments where abrasion resistance and dimensional stability are critical.

The 90–125 μm grain size range offers a balance between processing flowability and surface contact, making it ideal for refractory composites, ceramic fabrication, abrasive tools, and metal matrix reinforcements. It is chemically stable, non-toxic, and contains no radioactive elements, ensuring a safe and environmentally responsible material profile.
