Product Description SiC 97.8% black silicon carbide / ferro silicon carbide for Coated abrasivesSilicon carbide, also known as carborundum (SiC), is made from high-temperature resistance furnaces using quartz sand, petroleum coke (or coal coke). Silicon carbide also exists in nature as a rare mineral, moissanite . Silicon Carbide is also called Carborite. Among contemporary non-oxide high-tech refractory raw materials such as C, N, B, silicon carbide is the most widely used and economical one, which can be called gold steel sand or refractory sand. At present, silicon carbide produced by Chinese industry is divided into black silicon carbide and green silicon carbide.We can provice different grade,from 50% to 98%Advantages: 1. Corrosion resistance, high strength, high hardness.2. Good wear-resisting performance,resist to shock. 3. Silicon carbide is a cost-effective substitute for Ferrosilicon. 4.stable chemical performance, high thermal conductivity, high resistant temperaturePhysical And Chemical Analysis:PurposeSpecificationChemical Composition(%)Magnetic material (%)maxAbrasives grade SICminF.CmaxFe2O3max grain12-80980.200.60.0023 90-150970.300.80.0021 180-220970.301.20.0018 micropowder240-4000960.351.35-Refractory gradeGroup Size0-1mm1-3mm3-5mm5-8mm970.351.35- Fine Powder-180mesh-200mesh-240mesh-320mesh970.351.35-colorBlackHardness(mohs)9.15Melting point(°C)2250Maximum service temperature(°C)1900Ture density(g/cm3)3.9 ColorBlack ShapeAngularCrystal FormAlpha silicon carbide in hexagonal systemSpecific Gravity3.92Hardness 2750 kg/mm, 9.2 Mohs scaleMagnetic Material0.0065%Black Silicon Carbide Application For abrasives, grinding of electronics, metallurgical additive.For special ceramics, foam ceramicsFor auto parts, war industry and aviation, steelmakingFor abrasive and cutting tools and Cutting disks made of SiCFor grinding, honing, water-jet cutting and sandblasting.For lapping and polishing ,metallurgical additive and refractory material.Packaging & ShippingThe manufacturer supply best quality and good price of black siliconcarbure 1. in 25 kg small bag into 1 mt big, 1 big bag per pallet. 2. in 1 MT big bag on the pallet 3.
