摘要

The microwave dielectric properties of Sm(Co1/2Ti 1/2)O3 ceramics have been investigated. Sm(Co 1/2Ti1/2)O3 ceramics were prepared by conventional solid-state route. The dielectric constant values (r) saturated at 23.5-25.5. The Q×f values of 21,500-76,000 (at 10 GHz) can be obtained when the sintering temperatures are in the range of 1300-1420 °C. The temperature coefficient of resonant frequency τf was a function of sintering temperature. The r value of 25.5, Q×f value of 76,000 (at 10 GHz) and τf value of -16.3 ppm/°C were obtained for Sm(Co1/2Ti1/2)O3 ceramics sintered at 1360 °C for 4 h. For applications of high selective microwave ceramic resonator, filter and antenna, Sm(Co1/2Ti1/2) O3 is proposed as a suitable material candidate.
