Abstract
Modification of (Mg0.95Co0.05)TiO3ceramics by Ca0.61Nd0.78/3TiO3addition was investigated. The Ca0.61Nd0.78/3TiO3content plays a significant role in improving the dielectric properties. Microwave dielectric measurement showed an increase in dielectric constant (εr) and temperature coefficient of the resonant frequency (τf) and a decrease inQvalue with increasing Ca0.61Nd0.78/3TiO3content. By properly adjusting the Ca0.61Nd0.78/3TiO3content, zero temperature coefficient of resonate frequencyτfcan also be obtained. It becomes more promising in the application of wireless system.At 1375°C, the 0.85(Mg0.95Co0.05)TiO3-0.15Ca0.61Nd0.78/3TiO3ceramics possesses excellent microwave dielectric properties: a dielectric constant εr of 24.37, aQfvalue of 66200 ( at 7 GHz ) and a τf value of-1.4 ppm/°C.
