Ceramic

Kiln

Ceramic is the name for materials that are formed by the use of heat. The word ‘ceramic’ comes from the Greek word ‘keramikos’ (‘of pottery’). Ceramics broadly refers to all inorganic non-metallic materials which are formed by the action of heat. Up to the 1950s or so, the most important were the traditional clays, made into pottery, bricks, tiles and the like, also cements (binders that set and harden) and glass. A composite material of ceramic and metal is known as ‘cermet.’ Ceramic materials are typically hard, porous, and brittle.

Ceramic products are usually divided into four sectors: Structural (e.g. bricks, pipes, floor and roof tiles), Refractories (e.g. kiln linings, gas fire radiants, steel and glass making crucibles), Whitewares (e.g. tableware, wall tiles, decorative art objects and sanitary ware), and Technical ceramics (e.g. space shuttle heat shield tiles, gas burner nozzles, bullet-proof vests, nuclear fuel uranium oxide pellets, bio-medical implants, jet engine turbine blades, and missile nose cones).
