Black SiC  Refractories & Ceramics Material


1. Brief Introduction:

Silicon carbide (SiC), also known as carborundum /kɑːrbəˈrʌndəm/. It occurs in nature as the extremely rare mineral moissanite. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide such as light-emitting diodes (LEDs) and detectors in early radios were first demonstrated around 1907. 

Industrialized manufacture of silicon carbide involves smelting a hybrid of silica and petroleum coke in an electric resistance furnace, and smash it by types of crusher and sort it by designated meshes sieves. Black silicon carbide discriminates from green silicon carbide by appeared color and essential impurities.

2. Black Silicon Carbide As refractory and ceramics material

  By the virtues of good thermal expansion coefficient, extremely high liquifying temperature, stable chemistry nature,

and unusual high sublimation temperature, as well as the relatively cost-efficient price, it is a top choice for metallurgical industries.
