Silicon carbide is a super-hard material produced by smelting silicon dioxide with anthracite coal or pet coke in a melting furnace at temperatures ranging from 1800 to 2500 degrees Celsius for 50 to 200 hours. It boasts a hardness of 9.3 to 9.5 (with the Mohs scale topping at 10). It is characterized by its wear resistance, high hardness, high-temperature resistance, low expansion coefficient, and anti-oxidation properties.
Raw silicon carbide blocks can be divided into black silicon carbide and green silicon carbide due to variations in smelting materials.
Internationally, black silicon carbide and green silicon carbide are respectively designated by codes: C, GC.
Silicon carbide specifications are categorized internationally into European standards: FEPA standards, abbreviated as F, and Japanese standards: JIS standards.
European (FEPA) standards mainly include: F4#, F5#, F6#, F7#, F8#, F10#, F12#, F14#, F16#, F20#, F22#, F24#, F30#, F36#, F40#, F46#, F54#, F60#, F70#, F80#, F90#, F100#, F120#, F150#, F180#, F220#, F240#, F280#, F360#, F400#, F500#, F600#, F800#, F1000#, F1200#, etc.
Japan (JIS) standards primarily include: JIS#240, JIS#280, JIS#320, JIS#360, JIS#400, JIS#500, JIS#600, JIS#700, JIS#800, JIS#1000, JIS#1200, JIS#1500, JIS#2000, JIS#2500, JIS#3000, JIS#4000, JIS#6000, JIS#8000, and more.
Silicon carbide applications in abrasive field: Due to its hardness exceeding that of general metals and ceramics, silicon carbide is primarily used as an abrasive in processes such as polishing, grinding, cutting, and sandblasting. It boasts high abrasive efficiency, noticeable polishing effects, and fast cutting speeds. It can be used to process and fabricate materials like metals, gems, polycrystalline silicon, glass, ceramics, and more.
Silicon carbide applications in the abrasive tool industry:
Silicon carbide applications in abrasive tools: Abrasive tools made of silicon carbide are categorized into several major types based on different bonding agents, including resin-based, ceramic, coated, and other abrasive tools.
