More Information
Summary:The invention discloses a (MgZnCa) TiO3 microwave ceramic dielectric material and a preparation method thereof. The dielectric material consists of a host lattice, a modified additive, a sintering fluxing agent. The constitutional formula of the host lattice is Mgx (Zn(0-1/3)Ca(0-2/3))(1-x) TiO3 (x is more than or equal to 0.9, and less than or equal to 0.95); the modified additive is one or more selected from Nb2O5, Al2O3, MnO, Ni2O3, and Co3O4; and the sintering fluxing agent is one or more selected from B2O3, SiO2, K2O and Bi2O3. The microwave ceramic dielectric material prepared by adopting the quick preburning solid phase process has the characteristics of homogeneous material, uniform particle size distribution, high dispersion, good moulding process, and high quality factors. The microwave dielectric material meets the environmental requirements.
