GC, green silicon carbide, is a very high purity SiC lapping powder. The hexagonal α-type crystal is just below diamond in terms of hardness, and its chemical stability is excellent at room temperature. The result is a product with superior lapping and polishing capabilities, which is not affected by chemicals, and can spontaneously generate sharp grinding edges through fragmentation.

GC is well suited for use as a lapping powder in a wide range of functions, including the precision lapping and dicing of crystal and ferrite, the slicing of Si ingots, and the processing of materials ranging from ultra- hard metals and edged tools to soft metals such as brass and other copper alloys. Additionally, GC is used in the processing of various resins. GC is also ideal for use in super-finishing precision grindstones. As it possesses the electricalproperties of a semiconductor, GC has good heat conductivity and has the ability to withstand high temperatures, making it useful as a material in fine ceramics.
