Uporaba črnega silicijevega karbida

Since silicon carbide has stable chemical properties, high thermal conductivity, low thermal expansion coefficient and good wear resistance, it has many other uses besides being used as abrasive. For example, by using a special process to apply silicon carbide powder to the inner wall of the turbine impeller or cylinder body, it can improve its wear resistance and extend its service life by 1 to 2 times; the high-grade refractory material made from it is resistant to thermal shock, small in size, light in weight and high in strength, and has good energy-saving effect. Low-grade silicon carbide (containing about 85% SiC) is a good deoxidizer. It can speed up steelmaking, facilitate control of chemical composition and improve the quality of steel. In addition, Silicijev karbid se pogosto uporablja tudi pri proizvodnji silikonskih ogljikovih palic za električne grelne elemente .
Silicijev karbid ima veliko trdoto in odlično toplotno prevodnost . Je polprevodnik in se lahko upira oksidaciji pri visokih temperaturah .
