Notes:
Precursors of calcium strontium zirconate (Ca0.8Sr0.2ZrO3) were synthesized by oxalate coprecipitationmethod. TG-DTA was used to characterize the thermal decomposition behaviors of the precursors.The XRD results revealed that the powders crystallized as cubic Ca0.8Sr0.2ZrO3 with increasingheating temperature up to 1000ºC. Calcium strontium zirconate ceramics were obtained under conventionalsintering conditions by using the as-prepared Ca0.8Sr0.2ZrO3 powders. The SEM micrographs of theceramics sintered at 1450oC exhibited narrow grain-size distribution with the average grain size around0.7 4m. The dielectric properties showed that, dielectric constant of the Ca0.8Sr0.2ZrO3 was about 24.0 anddielectric loss was 0.002 at the frequency of 1GHz and the room temperature
