A novel compositions in the (1-x) Ca0.6Sm0.267TiO3–xSmAlO3 system were prepared via conventional mixed oxide route in order to modify the postive temperarure coefficient of resonnant frequency(ôf) of Ca0.6Sm0.267TiO3.The microwave dielectric properties and phase composition of this system ceramics were investigated. X-ray powder diffraction results showed that Ca0.6Sm0.267TiO3 and SmAlO3 formed a solid solution when 0.05≤x≤0.20. Microstructures of the sintered ceramics were observed by SEM; dielectric properties of the samples were also measured. The ôf values showed a near linear decrease with increasing additions of SmAlO3. A dielectric constant of 53.1, Qf value of 24,085GHz and ôf value of +13.3ppm/°C were obtained for 0.80 Ca0.6Sm0.267TiO3–0.20 SmAlO3 ceramics sintered at 1450°C for 4h.
