INTRODUCTION

Green silicon carbide is suitable for processing hard alloy, glass, ceramic and non-metallic materials, as well as semiconductor materials, high-temperature silicon carbon rod heating body, far-infrared external base materials, etc. The manufacturing method of green silicon carbide is the same as that of black silicon carbide, but the purity of raw materials used is higher, and it is also formed at a high temperature of about 2200 ° C in the resistance furnace. It is green, translucent, hexagonal crystal, and its Sic content is higher than that of black, Its physical properties are similar to those of black silicon carbide, but its properties are slightly more brittle than black silicon carbide. It also has good thermal conductivity and semiconductor properties.
