  • Ceramic materials — Ceramic Si3N4 bearing parts Ceramic materials are inorganic, non metallic materials and things made from them. They may be crystalline or partly crystalline. They are formed by the action of heat and subsequent cooling.[1] Clay was one of the… …   Wikipedia

  • Ceramic capacitor — In electronics, a ceramic capacitor is a capacitor constructed of alternating layers of metal and ceramic, with the ceramic material acting as the dielectric. The temperature coefficient depends on whether the dielectric is Class 1 or Class 2. A… …   Wikipedia

  • Dielectric — A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their …   Wikipedia
