carbide, any one of a group of compounds that contain carbon and one other element that is either a metal, boron, or silicon. Generally, a carbide is prepared by heating a metal, metal oxide, or metal hydride with carbon or a carbon compound. Calcium carbide, CaC 2, can be made by heating calcium oxide and coke in an electric furnace; it reacts with water to yield acetylene and is an important
With a single element, it is possible to scale-up the manufacturing process to make highly complex silicon chips in large volumes, and hence 80% of the world’s semiconductors use silicon. The remaining 20% use compound semiconductors, which coine two or more elements from the periodic table to form a compound.
Silicon is the second most abundant element in the Earth’s crust, after oxygen. It has atomic nuer 14, and occurs in the same group as carbon in the periodic table. Most rock consists of compounds of silicon, and sand consists largely of silica, or silicon dioxide (SiO2).

28/2/2012· This compound has a melting point of 2,870 C, and it is one of the hardest carbides. In Moh’s scale, it has a hardness value about 8.5-9 which is an extremely high value. One method of producing tungsten carbide is reacting tungsten with carbon at a very high temperature (1400–2000 °C).
In 1800, Davy thought silica to be a compound and not an element; but in 1811, Gay Lussac and Thenard probably prepared impure amorphous silicon by heating potassium with silicon tetrafluoride. In 1824 Berzelius, generally credited with the discovery, prepared amorphous silicon by the same general method and purified the product by removing the fluosilies by repeated washings.
