PRODUCT DESCRIPTION
Silicon carbide, exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found application in refractory linings and heating elements for industrial furnaces, and in semiconducting substrates for light-emitting diodes.
The modern method of manufacturing silicon carbide for the abrasives, metallurgical, and refractories industries is basically the same as that developed by Acheson. A mixture of pure silica sand and carbon in the form of finely ground coke is built up around a carbon conductor within a brick electrical resistance-type furnace. Electric current is passed through the conductor, bringing about a chemical reaction in which the carbon in the coke and silicon in the sand combine to form SiC and carbon monoxide gas. A furnace run can last several days, during which temperatures vary from 2,200° to 2,700° C (4,000° to 4,900° F) in the core to about 1,400° C (2,500° F) at the outer edge. The energy consumption exceeds 100,000 kilowatt-hours per run. At the completion of the run, the product consists of a core of green to black SiC crystals loosely knitted together, surrounded by partially or entirely unconverted raw material. The lump aggregate is crushed, ground, and screened into various sizes appropriate to the end use.
As an abrasive, silicon carbide is indispensable for creating abrasive tools, including grinding wheels, whetstones, grinding heads, and sand tiles, ensuring high precision and durability.
In metallurgy, silicon carbide serves as an exceptional deoxidizer and high-temperature resistant material, enhancing the quality and efficiency of metallurgical processes.
The high-purity single crystal form of silicon carbide is crucial for manufacturing semiconductors and silicon carbide fibers, paving the way for advanced technological applications.
