Black SiC

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 1000oC, 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.



This media is often sold by the drum (330#'s), which requires us to work up a custom freight quotation. Please use our Quote Request form for this. However, you can order small, 50lb pails online.
