Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 150–210 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with a particle size of 150–210 μm and purity exceeding 99.5% is an advanced ceramic-grade material known for its extreme hardness, excellent thermal resistance, and mechanical strength. Its coarser particle size makes it suitable for high-stress industrial applications such as foundry linings, heavy-duty abrasives, and structural refractories.

With a Mohs hardness rating of 9.5 and high thermal conductivity, this material offers stability under intense thermal and mechanical conditions. It is chemically inert in most environments, making it highly resistant to oxidation, corrosion, and wear. The material is free from toxic or radioactive components and does not contain heavy metals, offering both performance and safety in demanding applications.
