1/2# of 500/600 grit Silicon Carbide Fine/Pre-Polish- Stage #3 Grit for Rotary Tumblers or Stage #2 For Vibrating Laps and Vibrating Tumblers.

Black SiC is a man made mineral with a high thermal conductivity rating of 100 W/m-K. It is extremely hard, around a Mohs 9.1 or 2550 Knoop. It has high strength at elevated temperatures. For example, at 1000 degrees Celcius, SiC is 7.5 times stronger than Al203 (aluminum oxide). Black SiC will contain some free silicon and carbon and thus is not as pure as green SiC. Black will range in purity from 97-99% pure, depending on grit size.

Note: Any scales or containers do not come with this product.
