Ceramics are compounds between metallic and nonmetallic elements which can be oxides, nitrides, and carbides. The wide range of materials that falls within this classification includes ceramics that are composed of clay minerals, cement and glass. Up until past 40 or so years, the most important materials in this class were termed the “traditional ceramics”, those for which the primary raw material is clay. Products that are considered to be traditional ceramics are china, porcelain, bricks, tiles and in addition, glasses and high-temperature ceramics
Over the years, significant progress has been made in understanding the fundamental character of ceramics and of the phenomena that occur in them that are responsible for their unique properties. Consequently, a new generation of these materials has evolved, and the term “ceramic” has taken on much broader meaning. These new materials have a rather dramatic effect on our lives; electronics, computer, communication, aerospace and a host of other industries rely on their use.
