Green silicon carbide abrasive is one of the indispensable abrasives in industrial production. Green silicon carbide abrasive uses superior silica and petroleum coke as the main raw materials, and then adds salt as an additive, and is smelted at high temperature in an electric furnace.
The Mohs hardness of silicon carbide is 9.2~9.6, second only to diamond and boron carbide, and is a commonly used abrasive. Silicon carbide is mainly divided into black silicon carbide and green silicon carbide. Black silicon carbide has a lower hardness than green silicon carbide and is used to grind materials with lower hardness, such as cast iron and non-metallic materials; green silicon carbide is suitable for grinding cemented carbide, optical glass, titanium alloy and other materials.
Silicon carbide abrasives are divided into several categories according to the different adhesives, such as resin abrasives, ceramic abrasives, coated abrasives and other abrasives. Silicon carbide has a high hardness and can be prepared into various grinding wheels, sandpapers and abrasives for grinding, etc., mainly used in the mechanical processing industry.
Silicon carbide has the advantages of high grinding efficiency, obvious polishing effect, and fast cutting speed. As an abrasive, it is mainly used in polishing, grinding, cutting, sandblasting and other processes. Silicon carbide abrasives can process materials such as metals, gemstones, polysilicon, glass, and ceramics.
