Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 600–850 μm

Product Description:
This Silicon Carbide (SiC) Micron Powder features a coarse particle size distribution of 600–850 μm and a high purity of 99.5%+, making it ideal for industrial-scale applications requiring robust thermal resistance, high hardness, and chemical stability. With a Mohs hardness rating of 9.5 and excellent thermal conductivity, this grade of SiC is engineered for maximum performance in refractory systems and advanced composites.

Its large particle size is particularly suited for use in foundry applications, structural refractories, thermal spraying systems, and mechanical components exposed to high temperatures and corrosive environments. It also serves as an excellent aggregate in heat-dissipating composite materials and electronic insulators.
