Black silicon carbide lapping powder commonly known as Carborundum. Like GC, black silicon carbide is produced by reacting silica and coke in an electric furnace at a temperature greater than 2000° C. This produces the following qualities:
- An α‑type silicon carbide crystal configuration
- Stable cutting edges
- Ideal particle-size distribution
C is excellent for abrasive machining and produces superior lapping on a work surface. C is thus ideal as a material for precision-lapping polishing cloths and papers as well as precision grindstones.
