SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2600°C. 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%. Silicon Carbide Powder Feature1.Good oxidation resistance and chemical stability at high temperatures.2.High hardness with Mohs 9.2-9.3. Even at 2000oC, it's still get high strength.3.Excellent toughness.4.Low thermal conductivity. So it can resistant to themal shock.5.High purity min SiC content is 98.5%.6.High bulk density.7.Black silicon carbide grit is washed by water before milling process, so there is few impurities.Slicon Carbide Size Available0-1mm,1-3 mm, 3-5mm, 5-8mm,200-0mesh,325mesh,#60,#80,#100,#120,#180,#220,#240...Other special spec. could be supplied as required.Applications of black silicon carbide Sliding parts (mechanical seals, bearings, shafts)Crusher parts (classifier, airflow type crusher, beads mills)Semiconductor manufacturing equipment parts (XY stages, MOCVD trays, focus rings, water chucks)Molding machine parts (glass lens molding machine parts)Heat resistant parts (burner nozzles, high temperature testing machine parts, metal melting crucibles)Abrasion resistant parts (blast nozzles, shot blasting blades, buried pipe guard plates, fishing rod yarn paths) Detailed PhotosProduct ApplicationSilicon Carbide Powder ApplicationFor abrasive: Lapping, Polishing , Coatings, Grinding , Pressure blasting.For refractory: Refractory media for casting or metallurgical linings ,Technical Ceramics.For new-type application: Heat exchangers ,Semiconductor process equipment , Liquid filtration.Packaging & ShippingPackaging: 25kg/bag, two layers kraft bag with water proof, and with ton bag outside or each ton packed on a fumigation pallet according to customers' request.Company ProfileZhengzhou Rongsheng Refractory Material CO., LTD.Established in the early nineties of twenty century, with continuous innovation and development, now it is a comprehensive enterprise in refractory materials industry, covering metallurgy, building materials, electric power, chemical industry etc.We have own workshop , advanced production line , experienced workman and stricted check out flow .So choosing us is the right choice for you.If you are interested in our Low cement refractory castables or if you have any question, pls feel free to contact us at any time.
