摘要

The microwave dielectric properties of the (1 - x)(Mg0.95Co0.05)TiO3-xCa0.6La0.8/3TiO3 ceramic system prepared by mixed oxide route have been investigated. The crystal structures and the microstructures of the ceramics were characterized by means of X-ray and SEM. The microwave dielectric properties are functions of the sintering temperature as well as the composition. Alternation of phases between ilmenite-type structure and pseudo-cubic perovskite crystal is observed. The 0.9(Mg0.95Co0.05)TiO3-0.1Ca0.6La0.8/3TiO3 ceramics possesses excellent microwave dielectric properties with a dielectric constant εr of 21.86, a Q × f value of 131,000 GHz (at 7 GHz) and a τf value of -15.5 ppm/°C at 1350 °C/4 h. It is proposed as a suitable material candidate for applications requiring low microwave dielectric loss.
