Metallurgical grade black silicon carbide SiC particles for casting
Silicon carbide, also known as moissanite and emery, is an inorganic substance with the chemical formula SiC.
Silicon carbide is divided into black silicon carbide and green silicon carbide according to color.
According to the shape, there are silicon carbide blocks and silicon carbide powder.
Silicon carbide advantages:
(1) The smelting furnace is large, the smelting time is long, there are many crystals, the crystals are large, the purity is high, and there are few impurities.
(2) Good hardness and longer life.
(3) Chemical washing and water washing have good cleanliness.
(4) Specially treated products have higher purity, better toughness, and better grinding efficiency.
