Medium temperature stabilization type microwave dielectric ceramic material used in LTCC technology
The invention discloses a medium temperature stabilization type microwave dielectric ceramic material used in the LTCC technology. The chemical formula of the material is ZnZrTi3Nb2O14+(1-6)wt% CuO. At first, ZnO, ZrO2, TiO2 and Nb2O5 are weighed according to the ZnZrTi3Nb2O14 stoichiometric ratio, burnt at the temperature of 850 DEG C in advance after ball-milling, drying and sieving are carried out, and synthesized into frit; 1.55-2.05% of polyethylene and (1-6)wt% of CuO are added into the frit, and the mixture is compressed into a green body through pressure after ball-milling, drying and sieving are carried out; the green body is sintered at the temperature of 880 DEG C-920 DEG C, so that the intermediary agent temperature stabilization type microwave dielectric ceramic material is prepared. The low sintering temperature is adopted, and the material is a potential low-temperature co-fired ceramic material; the relative dielectric constant of the material is 40-43, the quality factor is 21, 400-32, 100 GHz, and the temperature coefficient of resonance frequency is minus 16*10<-6> DEG C-13*10<-6> DEG C; the preparation technology is simple, the process is free from pollution, and the material has a wide application prospect.
