Silicon carbide (-4) Anion
Super grade Raymond mill silicon carbide,it is produced from quartz sand and high quality anthracite under high temperature inan electric resistance furnace. It's SiC can be 98.5% Min ,F.C 0.2% Max ,can be as deoxidizer and high temperature resistant material and Refractory materials. If looks black and has a micro-hardness of 2800-3300kg/mm2, being used for produce the abrasive tools. It is also fit for process the grind metals and non-metals material of low tensile strength, such as grey cast iron, brass, aluminum, stone, leather and hard rubber etc. Also can be used as refractory materials and in electronic industry.
