Product Description

 

Silicon Carbide Grit

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.

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.

Black silicon carbide uses
Black silicon carbide can effectively deal with oxygen in molten steel during steelmaking. The condition that oxides float on the surface of molten steel is beneficial to improve the purity of molten steel. On the other hand, the use of black silicon carbide in the deoxidation of steelmaking can reduce the chance of defects. For example, subcutaneous bubbles and looseness.

Product Feature

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.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.

SIC is made from quartz sand and petroleum coke(smokeless acetylene) (salt added in the produce of green silicon carbide) as the mainraw material.it is made via light  resistance from hydrometallurgical,it is black opaque body hexagonal crystal and MOHS -hardness in the 915-9.5,which is after diamond and boron carbide with crisp and sharp performance and certain degree of conductive heat.
