Carbide is a chemical compound composed of carbon and a less electronegative element, often a metal. One of the most common types is calcium carbide, which is used in the production of acetylene gas for welding and cutting. Carbides are known for their hardness and high melting points, making them valuable in industrial applications. Another well-known carbide is tungsten carbide, which is widely used in cutting tools and jewelry due to its exceptional durability. Carbides can also be found in various forms, such as silicon carbide, used in abrasives and electronic devices, showcasing their versatility in different industries.
