About silicon carbide

In industrial production, silicon carbide smelting blocks usually use quartz, petroleum coke etc as raw materials, through grinding and other processes to form a charge with a reasonable ration and a suitable particle size (An appropriate amount of wood chips needs to be added to prepare green silicon carbide when adding appropriate amount of stable salt), it is prepared by high temperature, and the thermal equipment for preparing silicon carbide smelting block at high temperature is a special silicon carbide electric furnace, the refined silicon carbide block is crushed, washed by acid and alkali, magnetic separation and sieving or water separation to make products of various sizes.

Different grade of silicon carbide

According to the content of silicon carbide, it can be divided into first grade, second grade and third grade silicon carbide. The main component of second grade silicon carbide is 90%~95% ,but the crystal body is small and very fragile and cannot be used as an abrasive.It can be used for casting), The first-grade silicon carbide layer (SiC content <96%, and is a coarse crystalline body of hexagonal silicon carbide), and the first-grade silicon carbide layer becomes after classification, coarse crushing, fine crushing, chemical treatment, drying and screening, magnetic separation Black or green silicon carbide particles of various particle sizes. The silicon carbide fine powder is prepared through the water separation process; to be made into silicon carbide products, it also undergoes the process of forming and sintering, and the three-level silicon carbide is used for steel-making.
