Oxide ceramics are technical Ceramics and are thus categorised as non-metallic mineral materials. The particles in oxide ceramic masses are held together by ionic bonding. Oxide ceramics are inorganic compounds of metallic or metalloid elements with oxygen. Oxides can be combined with nitrogen or carbon to form more complex oxynitride or oxycarbide ceramics. Oxide ceramics have high melting points, low wear resistance, and a wide range of electrical properties. The minerals used to make these ceramic materials are crushed or ground into a fine powder that is purified by adding it to a solution and allowing a chemical precipitate to form.
