Low-Fire Processing (1-x)Mg0.95Co0.05TiO3 - xCa0.6La0.8/3TiO3 Microwave Dielectric Ceramics


Article Preview

The effects of 3Z2B addition on the microwave dielectric properties and the microstructures of (1-x)(Mg0.95Co0.05)TiO3-xCa0.6La0.8/3TiO3 ceramics prepared with conventional solid-state route have been investigated. Doping with 3Z2B can effectively promote the densification and the microwave dielectric properties of (1-x)(Mg0.95Co0.05)TiO3-xCa0.6La0.8/3TiO3 ceramics. It was found that (1-x)(Mg0.95Co0.05)TiO3-xCa0.6La0.8/3TiO3 ceramics can be sintered at 1150°C due to the liquid phase effect of 3Z2B additions observed by SEM. The Q×f value of (1-x)(Mg0.95Co0.05)TiO3-xCa0.6La0.8/3TiO3 ceramics decreased with increasing 3Z2B content. At 1150°C, 0.9(Mg0.95Co0.05)TiO3-0.1Ca0.6La0.8/3TiO3 ceramics with 1.0wt% 3Z2B addition possesses a εr value of 22.6, a Qf value of 49,000 (GHz) and a τf value of-10.7 ppm/°C.
