Ceramics comprise a wide range of materials, which have found a great variety of applications due, for example, to their hardness and refractory properties (i.e., resistance to heat and corrosion). Ceramics, from the materials science point of view, include all nonmetallic inorganic solids that may contain as constituents both metallic and nonmetallic elements held together by mixed ionic and covalent bonding. With this definition, even semiconductors, phosphors, and minerals would be considered as ceramic materials, so some materials that are often considered as ceramics are treated in other chapters.
