Dielectric ceramics are mainly used in the production of ceramic capacitors and microwave dielectric components. In the dielectric ceramics such as TiO2, MgTiO3 and BaTiO3 and rare earths such as La, Functional Ceramics Nd and Dy, the dielectric properties can be improved remarkably.

As in the BaTiO3 ceramics with high dielectric constant, La, Nd rare earth compounds with dielectric constant ε = 30 ~ 60 can maintain the dielectric constant in the wide temperature range, and the service life of the device is improved obviously. In the dielectric ceramic for thermal compensation capacitors, Functional Ceramics rare earth can be added as necessary to achieve the improvement of the ceramic dielectric constant, temperature coefficient, quality factor improvement or regulation, and expand its application range. Functional Ceramics The MgO · TiO2-La2O3-TiO2 ceramics and CaTiO3-MgTiO3-La2TiO5 ceramics were modified by La2O3 on the thermostatic capacitors of magnesium titanate ceramics, that is, the original dielectric loss and temperature coefficient were small , The dielectric constant has also been significantly improved.

Microwave dielectric ceramic variety, Functional Ceramics mixed with rare earth oxide BaO-RE2O3-TiO2 ceramic is a more common application of dielectric materials, the dielectric constant ε can be more than 80. The dielectric constant ε can be up to 8000, and the dielectric constant ε of Nd2Ti2O7- (BaPb) TiO3-TiO2 ceramics can reach 90%. Due to the application of new technology, with the development of new ceramics such as BaO-TiO2-SnO2-RE2O3 system, Functional Ceramics the main technical indicators of microwave ceramic dielectric materials are eager to achieve in recent years: Qε value is about one order of magnitude higher than that of present, that is, 10000; ε in the range of 2 ~ 2000 series to adapt to a variety of purposes; temperature coefficient αε in the range of 300 ~ -100 series, can be more easily obtained zero temperature coefficient of dielectric resonators and filters and other microwave devices The

Sensitive ceramic is an important one of functional ceramics, Functional Ceramics which is characterized by some external conditions such as voltage, gas composition, temperature, humidity and other reactions sensitive, it can be related to the relevant electrical performance parameters of the reaction or change to achieve the circuit, Process or environmental monitoring, widely used in the control circuit of the sensor components, it is also known as the sensor ceramic. Rare earth and the performance of such ceramics there is a close relationship between.

Intelligent ceramics is a self-diagnosis, Functional Ceramics self-adjustment, self-recovery, self-conversion and other characteristics of a class of functional ceramics. Lithium zirconate titanate (PLZT) ceramics obtained by adding rare earth lanthanum to lead zirconate titanate (PZT) ceramics as described above are not only an excellent electro-optical ceramic, but also because of their shape memory function, Functional Ceramics Shape self-recovery self-tuning mechanism, it is also a smart ceramic. Functional Ceramics The concept of intelligent ceramic materials, advocated a new concept of the development and design of ceramic materials, Functional Ceramics to broaden the application of rare earth in modern functional ceramics is extremely beneficial.
