Silicon Carbide Block
It is produced from quartz sand and high quality anthracite under high temperature in an electric resistance furnace. It 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.
Silicon Carbide Powder
Silicon carbide powder of SiC 98.0% min ,Fe2O3 is 0.08% max,particle size can pass 100-180mesh sieve . This product also known as silicon carbide sand,generally divided into mesh grade sand from 8#-320#,the greater the number is,the smaller particle size it is. Silicon carbide particle size of sand is dvided into green and black. It is the ideal for abrasive material,mainly used in polishing and grinding wheel,cutting slices,and etc sectors in abrasive industry.
