Carbură de siliciu negru

SiC negru 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 sau 2550 Knoop. It has high strength at elevated temperatures. De exemplu, at 1000oC, SiC is 7.5 times stronger than Al203 (oxid de aluminiu). 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. Green SiC is made from Silica sand and coke and is extremely pure. Hexagonally shaped, it breaks into very sharp particles. Our green SiC is 99% pure, exceeding JIS, ISO, & FEPA standards.

Carbură de siliciu verde

SiC verde is harder than black, coming in at a 9.4 Mohs and 2600 on the Knoop scale. Green is often the media of choice when it comes to wire sawing.The material is water classified/separated – this produces a very tight particle size distribution, as well as a reduction in fines, as preferred for accurate wire sawing applications. Unless your application requires an extremely pure SiC, by default, black is preferred due to its more economic pricing.
