Non-oxide ceramics are a class of materials primarily composed of compounds that do not contain oxygen. Common examples include carbides, nitrides, and borides. These ceramics are known for their high hardness, thermal stability, and resistance to wear, making them suitable for applications in cutting tools, aerospace components, and electronics. Unlike oxide ceramics, which are often brittle, non-oxide ceramics can exhibit improved toughness and strength. Their unique properties arise from the strong covalent or metallic bonds present in their structures. This makes them valuable in industries requiring materials that can withstand extreme conditions, such as high temperatures and corrosive environments.
