Tungsten carbide (WC), also referred to as cemented carbide, is a composite material manufactured by a process called powder metallurgy. Tungsten carbide powder, generally ranging in proportion between 70%-97% of the total weight, is mixed with a binder metal, usually cobalt or nickel, compacted in a die and then sintered in a furnace.
Metallurgical Grade (82 - 92) Our production process inherently produces grades of silicon carbide with lower SiC content, material ideally suited to re carburetion of cast iron and steel in foundries. Metallurgical grade Silicon carbide can also be used to enhance
The silicon produced via this process is called metallurgical grade silicon and is at least 98% pure. Using this method, silicon carbide (SiC) may also form from an excess of carbon in one or both of the following ways: SiO 2 + C → SiO + CO or SiO + 2 C → SiC + CO.
Silicon carbide (SiC) is a synthetic compound which is commercially produced by heating a mixture of metallurgical coke and high-purity silica sand to 2,400° C in an electrical resistance furnace. A method to produce SiC was first discovered in this country by E. G. Acheson in 1891 while studying the reaction of carbon with other materials. The first patent on the manufacture of SiC was
That silicon is then treated with oxygen to remove impurities such as calcium or aluminium, leaving what''s known as metallurgical grade silicon. That''s up to 99% pure.
Processes for Upgrading Metallurgical Grade Silicon to Fesil Sunergy process in Norway is based on the use of pure raw materials (low in B and P) appliion for SoG-Si production In this process high purity silicon carbide is first produced and then used for the

Silicon Carbide Bricks Introduction Silicon carbide bricks as a kind of hot-sale refractory bricks for high temp furnace appliion in Non-ferrous metal smelting industry,steel industry, metallurgical industry in Rongsheng factory manufacturing with silicon carbide
Silicon is a solid at room temperature, with relatively high melting and boiling points of 1414 and 3265 C, respectively. Like water, it has a greater density in a liquid state than in a solid state, and so, like water but unlike most substances, it does not contract when it freezes, but expands.
