Silicon carbide

Silicon carbide (CAS 409-21-2), or SiC, is a synthetically produced abrasive and refractory material for high-temperature and high-wear industrial environments.

Where is Silicon carbide used?

• Abrasives: grinding wheels, cutting discs, sandpapers and blasting media for hard metals, ceramics and composites
• Refractories: kiln furniture, furnace linings and crucibles that withstand thermal cycling
• Electronics and semiconductors: SiC wafers and substrates for power devices, inverters and EV drivetrain components
• Metallurgy: deoxidizer and carbon/silicon additive in steel and cast iron production
• Particle size is the primary specification variable.

Good to know: Black SiC and green SiC are the two commercially recognized variants, differentiated by purity level. Grades include metallurgical, refractory and semiconductor, each with distinct purity thresholds.
