The manufacturing method of green silicon carbide is the same as that of black silicon carbide, but the raw materials used are of high purity. It is also formed at a high temperature of about 2200 ° C in a resistance furnace. It is green, translucent, and hexagonal, and its Sic content is higher than black. , Physical properties are similar to black silicon carbide, but the performance is slightly more brittle than black, and also has good thermal conductivity and semiconductor characteristics.
