Low-temperature sintered microwave dielectric ceramic material and preparation method thereof
A low-temperature sintered microwave dielectric ceramic material and a preparation method thereof are provided. The ceramic material includes a base material and a low-melting-point glass material; a general chemical formula of the base material is (Zn0.9Cu0.1)0.15Nb0.3(Ti0.9Zr0.1)0.55O2; a percent by weight of the low-melting-point glass material is in a range of 1 wt. % to 2 wt. %; chemical compositions of the low-melting-point glass material include A2CO3-M2O3—SiO2, A of which includes at least two of a lithium ion, a sodium ion, and a potassium ion, M of which includes at least one of a boron ion and a bismuth ion; and a sintering temperature of the ceramic material is in a range of 850° C. to 900° C. The microwave dielectric ceramic material has the advantages of low dielectric loss, simple and controllable process, etc., has good process stability, and can meet requirements for radio communication industry.
