초록
(Ca0.7Sr0.3)(Zr0.8Ti0.2)O3 ceramics were fabricated on conventional mixed oxides method. The experimental results show that sintering temperature strongly affects the microstructure and dielectric properties of CSZT ceramics. The optimum sintering temperature was 1450 o C, exhibiting relatively high dielectric constants and quality factors in wide frequency ranges (51.7 and 1379) (at 1 MHz), (50.1 and 1328) (at 3.5 GHz). Also, CSZT ceramics sintered at 1450 o C meets C0G characteristic (± 30 ppm/ o C, -55o C ~ 125 o C). These results indicated that CSZT ceramics can be applied to materials for microwave ceramics.
