Use of silicon carbide
by admin on 22-08-23
Silicon carbide is also known as gold steel sand or refractory sand. Silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips (production of green silicon carbide needs to add salt) and other raw materials in the resistance furnace by high temperature smelting. At present...
