SiC Powder (Silicon Carbide)
Up to 1600°C
Main applications
- SiC powder for refractories
- abrasives and semiconductors
Key Features
Ultra-hard — Mohs hardness 9.5
Silicon carbide is the hardest material after diamond (10) — an essential raw material for hard abrasives and wear-resistant ceramics
1600°C refractory ceramic raw material
An inorganic ceramic — heat resistant to 1600°C in inert atmospheres, a raw material for refractories and high-temperature sintered bodies
High thermal conductivity ceramic
The high thermal conductivity characteristic of silicon carbide — a raw material for heat-dissipating ceramics and semiconductor thermal components
Semiconductor and electronics raw material
High-purity SiC powder — raw material for CMP slurries in wafer polishing and for SiC substrates and power semiconductors
Custom particle size and purity
From a few microns to a few hundred microns at 97%+ purity — supplied to the grade your abrasive, sintering or electronics use requires
