In the electronic industry can use electrical, magnetic ceramics, known as electronic ceramics. Electronic ceramics have new functions through the precise control of the surface, grain boundary and size structure. It can be widely used in energy, household appliances, automobiles, etc.

Electronic ceramic substrate material in electronic ceramics, occupies the most important position is insulator. In particular, high purity dense alumina sintered body with size precision of micron or below can be used as insulating substrate or packaging material for advanced integrated circuit. High purity dense alumina with metal materials do not have the insulation and polymer materials do not have thermal conductivity.

Ceramic piezoelectric materials piezoelectric elements can be used to convert electrical and mechanical signals. The piezoelectric ceramic elements with certain shape are mainly made of PbTiO3-PbZrO3 (PZT) system by sintering. Even the sintered body can obtain the piezoelectric properties of single crystal by polarization. The main uses of piezoelectric elements are spark plugs and resonators. Resonator plays the role of selective passing through a specific frequency wave filter, is an indispensable component of television (TV), radio and other tuning circuits.

Ceramic semiconductor Materials In ceramics, semiconductors are many. The temperature - dependent property of resistance can be used for nonlinear resistance. The negative temperature coefficient nonlinear resistance (NTC nonlinear resistance) decreases with the increase of temperature and has general semiconductor characteristics. Oxide ceramics of ferrous metals, because of their chemical and thermal stability, can be used in nonlinear resistors to control temperatures over a wide range. In contrast, components called positive temperature coefficient thermistors (PTC thermistors) are made of semiconducting BaTiO3 ceramics. Since the resistance of such ceramics increases sharply at the phase transition temperature, it is convenient for them to automatically control the temperature near the phase transition temperature if they are used as resistance heating elements.
