Silicon Carbide 98% Black Grit

Silicon Carbide 98% Black Grit (CAS 409-21-2, molecular formula SiC) is a raw material for tile, sanitaryware, tableware and refractory production, where particle size and impurity profile drive fired colour and body strength. China Chemicals supplies it at 98% min in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as Carborundum, Black SiC, Silicon Monocarbide. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Abrasive blasting, lapping and grinding media
Refractory kiln furniture and shelving
Deoxidiser and inoculant in foundry melts
Wear-resistant technical ceramic components
Heating element and semiconductor substrate manufacture
