Abstract

The invention discloses a high-dielectric microwave dielectric ceramic and a preparation method thereof, the chemical composition expression of the ceramic is aLi2O.bCoO.cLn2O3.dNb2O5.eCeO2 (I), and Ln is equal to Y, La or Sm. The microwave dielectric ceramic contains oxides of rare earth elements Y, La or Sm and has good microwave dielectric properties, and the microwave dielectric ceramic obtained by sintering the two oxides of the rare earth elements, Nb2O5 and CeO2 together has good microwave dielectric properties.

Description

technical field [0001] The invention relates to the field of ceramic materials, in particular to a high-medium microwave dielectric ceramic and a preparation method thereof. Background technique [0002] The ultimate goal of communication is to be able to "connect with anyone at any place and at any time", that is to say, to exchange and transmit information in all time and space. This requirement will inevitably push mobile communication to an extremely important development position, thereby promoting the development of communication devices in the direction of portability, mobility and miniaturization. At the same time, in order to meet the increasing number of users, it is necessary to develop in the direction of high carrier frequency. This rapid development of mobile communications to higher frequencies has led to an urgent demand for related devices such as microwave filters, resonators, phase shifters, microwave capacitors, and microwave dielectric substrates. Micr...
