Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 1400–2000 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with a coarse particle size of 1400–2000 μm and 99.5+% purity is an ideal material for high-performance industrial and structural applications requiring extreme thermal resistance and mechanical durability. Its robust grain structure ensures long-lasting performance in abrasive and refractory systems, while maintaining chemical inertness under harsh conditions.

Thanks to its exceptional hardness (9.5 Mohs) and high thermal conductivity, this SiC powder is widely used in demanding applications across ceramics, aerospace, energy systems, and precision engineering. It is non-toxic, free from heavy metals and radioactive elements, and safely stored under vacuum in dry conditions.
