Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 125–180 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with a particle size range of 125–180 μm and purity of 99.5+% is a highly durable and thermally conductive material, ideal for advanced industrial and structural applications. Its coarse particle structure makes it especially effective in manufacturing high-strength ceramics, precision abrasives, and heat-resistant components for demanding environments.

Thanks to its excellent hardness (9.5 Mohs), superior thermal stability, and low compressibility, this material is widely used in applications that require resistance to extreme heat, mechanical wear, and chemical corrosion. It is a non-toxic, non-radioactive compound free from heavy metals, making it safe for long-term technical usage.
