Carbide is a chemical compound made up of carbon and a less electronegative element, often a metal. It is known for its hardness and high melting point, making it useful in various industrial applications. Common types of carbides include calcium carbide, used in producing acetylene gas, and tungsten carbide, which is widely used in cutting tools and abrasives. Carbides can be formed through different methods, including direct combination of elements or through chemical reactions. They are important in manufacturing processes, especially in the production of ceramics and hard metals, due to their durability and resistance to wear.
