Premium Black Silicon Carbide98%: High Purity for Enhanced Abrasive Performance¹

Product Description Silicon carbide includes black silicon carbide and green silicon carbide, among which: black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, which are smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. Green silicon carbide is made from petroleum coke and high-quality silica as the main raw material, adding salt as an additive, and smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.Black Silicon Carbide is brittle and sharp. It has a good electrical and heat conductivity. Its Knoophandness is 3100-3280kg/mm2. Green Silicon Carbide is a synthetic brittle carborundum with high thermal conductivity and high strength which get no decrease in 1000oC( 7.5 times stronger than Alumina)Green silicon carbide is characterized by extreme hardness (Mohs 9.4/2600 Knoop) which only ranks after CBN and B4C.The abrasives made of silicon carbide are suitable for working on cast iron,non-ferrous metal,rock, leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive.Black Silicon Carbide ItemSiCFe2O3Free CarbonSiO2SiC97≥97%≤1.0%≤0.5%≤1.5%SiC95≥95%≤1.5%≤1%≤2.5%SiC92≥92%≤2.0%≤2.5%≤3.5%SiC90≥90%≤2.5%≤3%≤4.0%Green Silicon Carbide SiC99≥99%≤0.2%≤0.2%-Grit Size and StandardStandardParticle SizeSiC ≥ (%)F.C ≤ (%)Fe2O3 ≤ (%)GBF4-F90;P12-P10099.100.200.20JIS8# - 220#98.0//OCT10#;12#98.00.4(Fe) 0.3GBF320-F500; P40097.50.300.50JIS240# - 3000#96.0//OCTM40-M1498.00.4(Fe) 0.2FAQQ1: Are you trading company or manufacturer?A: We are manufacturer.Q2: Are samples free or not?A: Sample can be free of charge. Only shipping needs to be paid by your side. Q3. Can you customize the grain size or parameters according to my requirement?A: Yes, we can customize.Q4. Do you test all your goods before delivery?A: We have laboratories to test the chemical and physical properties of our SiC. We will repeatedly test during production and before shipping to ensure that the product meets the appointed standards. Looking forward to receiving your inquiry.Please feel free to ask me if you have any questions. Thank you ^^
