The hardest blasting medium Silicon Carbide Grit

Short Description:

Silicon Carbide Grit

Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance, silicon carbide has many other uses besides being used as abrasives. For example, silicon carbide powder is applied to the impeller or cylinder of a water turbine by a special process. The inner wall can improve its wear resistance and prolong its service life by 1 to 2 times; the high-grade refractory material made of it has heat shock resistance, small size, light weight, high strength and good energy-saving effect. Low-grade silicon carbide (containing about 85% of SiC) is an excellent deoxidizer.

Product Description

Junda Silicon Carbide Grit is the hardest blasting media available. This high-quality product is manufactured to a blocky, angular grain shape. This media will break down continuously resulting in sharp, cutting edges. The hardness of Silicon Carbide Grit allows for shorter blast times relative to softer medias.

Low-grade silicon carbide (containing about 85% of SiC) is an excellent deoxidizer. It can speed up the steelmaking speed, and facilitate the control of chemical composition and improve the quality of steel. In addition, silicon carbide is also widely used to make silicon carbide rods for electric heating elements.

Silicon carbide has a very high hardness, with a Mohs hardness of 9.5, second only to the world's hardest diamond (10). It has excellent thermal conductivity, is a semiconductor, and can resist oxidation at high temperatures.
