Abstract
Abstract The (1− x )MgTiO 3 (MT)– x (Ca 0.8 Sr 0.2 )(Zr 0.1 Ti 0.9 )O 3 (CSZT) ceramic system prepared by using the conventional solid state method was investigated in terms of its microstructures and microwave dielectric properties. To achieve a temperature-stable material, two compounds with negative and positive temperature coefficients were used to form mixed phases. The microwave dielectric properties are strongly correlated with composition. For practical application, a dielectric constant ( e r ) of 22.1, a quality factor ( Q × f value) of 116,000 GHz, and a temperature coefficient of resonant frequency ( τ f ) of 5 ppm/°C for 0.95MgTiO 3 –0.05(Ca 0.8 Sr 0.2 )(Zr 0.1 Ti 0.9 )O 3 sintered at 1300° C for 4 h are proposed.
