Silicon Carbide Ceramic Material Supplier

SiC exists in nature as the extremely rare mineral called moissanite, while most of this material is synthesized in factories. As SiC is extremely hard, It has been mass produced as abrasive since late 19th century. Silicon carbide powder has a black color when the purity is low and products with purity higher than 90% is green. SiC grains can be bonded together by sintering to form ceramic

Electric Discharge Machining for Silicon Carbide and

In order to cut the ingots and slabs of the silicon carbide (SiC), we developed the new method of electric discharge machining (EDM). EDM is usually used for the machining of the metals, and if it is electric conductive material, it is effective for the machining. However, if the electrical resistivity of SiC is high, the electric current cannot be large enough for and the EDM, and we failed
