Low Temperature Sintering of Ca0.6La0.8/3TiO3-Li0.5Nd0.5TiO3 Ceramics with ZnO-B2O3-SiO2 Glass Addition
The sintering behaviors and microwave dielectric properties of the Ca0.6La0.8/3TiO3-Li0.5Nd0.5TiO3 (abbreviated CLLNT) ceramics doped by small amounts of ZnO-B2O3-SiO2 glass were investigated in this paper. The adding of ZnO-B2O3-SiO2 glass improved the densifications of the CLLNT ceramics and the sintering temperature of the CLLNT ceramic had been efficiently lowered to 1050°C. Especially, the 8wt% ZnO-B2O3-SiO2 glass doped CLLNT ceramic sintered at 1050°C for 3 h has optimum microwave dielectric properties of Kr=89, Q×f=1445GHz, and TCF=11.4 ppm/°C and it should be a suitable candidate for LTCC applications.
