Silicon Carbide Key Advantages
- High hardness & wear resistance
Mohs hardness ~9.4, second only to diamond, providing stable and efficient material removal.
- Narrow particle size distribution
Uniform grain size ensures scratch-free, consistent surface finish.
- Excellent self-sharpening property
Grains micro-fracture during polishing to maintain sharp cutting edges without smearing.
- High thermal conductivity
Effectively dissipates heat, preventing burning, discoloration, or cracking of workpieces.
- High chemical purity
Low iron and impurity content avoids staining, blackening, or chemical reactions with polished surfaces.
- Suitable for dry & wet polishing
Widely used in slurry, polishing paste, and bonded abrasive tools.
Silicon Carbide Typical Applications
- Marble, granite, engineered stone mirror polishing
- Glass and optical component finishing
- Ceramic and precision carbide lapping
- Stone floor restoration and crystal surface treatment
