Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 1200–1700 µm

Product Description:
Silicon Carbide (SiC) Micron Powder with a particle size range of 1200–1700 µm and a purity exceeding 99.5% is a high-performance ceramic material known for its extreme hardness, excellent thermal conductivity, and superior resistance to chemical corrosion. Its robust physical and thermal characteristics make it highly suitable for demanding applications in industrial processing, electronics, and high-temperature structural components.

This coarse-grade SiC powder is ideal for use in structural ceramics, refractory linings, and wear-resistant components such as grinding wheels, seal rings, and nozzles. The material’s high thermal conductivity and low thermal expansion ensure dimensional stability in high-heat environments, while its outstanding mechanical strength allows for use in composite reinforcement and abrasives. Additionally, Silicon Carbide is chemically inert, non-toxic, non-radioactive, and free from heavy metals, making it safe for industrial and environmental applications.
