Green SIC for electric heating element silicon carbon rod
Description
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.
