Siyah silisyum karbür kuvars kumundan yapılmıştır, petroleum coke and silica as the main raw material, through the resistance furnace high temperature smelting. Sertliği korundum ile elmas arasındadır., mekanik mukavemet korundumdan daha yüksektir, kırılgan ve keskin.
What are the properties of black silicon carbide provided by black silicon carbide manufacturers? Let’s learn more about it with Henan Superior Abrasive.
Black silicon carbide advantages
Siyah silisyum karbür, with metallic luster, contains more than 95% SiC, with greater strength than green silicon carbide, but lower hardness, mainly used for grinding cast iron and non-metallic materials.
Molecular formula is SiC, its hardness is between corundum and diamond, mekanik mukavemet korundumdan daha yüksektir, can be used as abrasives and certain other industrial materials. Industrial silicon carbide was successfully developed in 1891 and is an early man-made abrasive. Although a small amount of silicon carbide exists in meteorites and the earth’s crust, no mining source has been found to date.
Siyah silisyum karbür yaklaşık içerir 98.5% SiC, its toughness is higher than that of green silicon carbide, and is mostly used for processing materials with low tensile strength, cam gibi, seramik, taş, ısıya dayanıklı malzemeler, dökme demir ve demir dışı metaller.
Silicon carbide advantages
Due to its stable chemical properties, yüksek ısı iletkenliği, düşük termal genleşme katsayısı ve iyi aşınma direnci, silisyum karbür is used as an abrasive, but also has many other uses, örneğin: a special process to silicon carbide powder coated in the impeller of a hydraulic turbine or the inner wall of the cylinder body, which can improve its wear resistance and extend the service life of 1 ile 2 zamanlar; used to make refractory materials, heat shock, small size, light weight and high strength, good energy-saving effect. Low-grade silicon carbide (containing about 85% SiC) is a better deoxidizer, which can accelerate the speed of steelmaking, and facilitate the control of chemical composition, çelik kalitesini artırmak. Ek olarak, silicon carbide is also used in large quantities to make electric heating elements silicon carbon rods.
Silicon carbide is very hard, has excellent thermal conductivity, is a semiconductor, and can resist oxidation at high temperatures.
