This product is made of brown corundum powder, which is extruded under high pressure and sintered at high temperature. It has moderate hardness, is clean and not easily broken, Repeated use results in

Silicon carbide has four main application areas, namely functional ceramics, advanced refractory materials, abrasives, and metallurgical raw materials.

The technical conditions for abrasive grade silicon carbide shall comply with GB/T 2480-2008. The chemical composition of each brand is given in Tables 6-6-47 and 6-6-48.

China's silicon carbide export market is mainly in Asia and North America, with export shares accounting for 70.25% and 23.76% of global export shares, respectively.

There are over 200 silicon carbide smelting enterprises in China, with an annual production capacity of over 2.2 million tons (including more than 1.2 million tons of green silicon carbide blocks and

The common method is to mix quartz sand with coke, use the silicon dioxide and petroleum coke in it, add salt and sawdust, place them in an electric furnace, heat them to a high temperature of about 2

Pure silicon carbide is a colorless and transparent crystal. Industrial silicon carbide appears light yellow, green, blue, and even black due to different types and contents of impurities, and its tra

Due to its stable chemical properties, high thermal conductivity, low coefficient of thermal expansion, and good wear resistance, silicon carbide has many other uses besides being used as an abrasive.

Silicon carbide has two commonly used basic varieties: black silicon carbide and green silicon carbide, both of which belong to the α- SiC。① Black silicon carbide contains about 95% SiC, and its tough

Silicon carbide is a type of carbide that was accidentally discovered by American Acheson in the laboratory during the electric melting diamond experiment in 1891. At that time, it was mistakenly beli

Ferrosilicon is widely used in the steel industry, casting industry, and other industrial production.

Ferrosilicon is made by smelting coke, steel shavings, quartz (or silica) as raw materials in an electric furnace. Traditional smelting of ferrosilicon involves reducing silicon from silica containing
