Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 850–1200 μm

Product Description:
This high-purity Silicon Carbide (SiC) micron powder features a coarse particle range of 850–1200 μm and a purity level exceeding 99.5%, making it an excellent choice for demanding industrial and refractory applications. With outstanding thermal conductivity, a Mohs hardness of 9.5, and resistance to thermal shock and chemical corrosion, this material excels in extreme environments.

The larger grain size enhances its utility in structural ceramics, heavy-duty kiln linings, and thermal spraying applications. It also serves as a robust thermal and mechanical filler in composite systems, boosting overall strength, heat dissipation, and dimensional stability. Free from toxic and radioactive substances, this SiC grade meets strict safety and environmental standards.
