Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 10–25 µm

Product Description:
Silicon Carbide (SiC) Micron Powder with 99.5+% purity and a particle size distribution of 10–25 µm is a high-performance ceramic-grade material widely recognized for its extreme hardness, high thermal conductivity, and chemical inertness. With a hardness of 9.5 on the Mohs scale, this material is suitable for applications requiring abrasion resistance, structural strength, and thermal stability.

Thanks to its reliable grain size and excellent thermal shock resistance, this SiC powder is used in the fabrication of advanced ceramics, high-precision grinding tools, and components operating in high-temperature environments. It offers excellent durability under extreme conditions and does not degrade when exposed to acids, alkalis, or oxidation.
