Abstract

The microwave dielectric properties of Sm(Zn_1/2Ti_1/2)O₃ ceramics have been investigated. Sm(Zn_1/2Ti_1/2)O₃ ceramics were prepared by conventional solid-state route with various sintering temperatures and times. The prepared Sm(Zn_1/2Ti_1/2)O₃ exhibited a mixture of Zn and Ti showing 1:1 order in the B-site. Higher sintered density of 7.01 g/cm³ can be produced at 1310 °C for 2 h. The dielectric constant values (ε_r) of 22-31 and the Q × f values of 4700-37,000 (at 8 GHz) can be obtained when the sintering temperatures are in the range of 1250-1370 °C for 2 h. The temperature coefficient of resonant frequency τ_f was a function of sintering temperature. The ε_r value of 31, Q × f value of 37,000 (at 8 GHz) and τ_f value of -19 ppm/°C were obtained for Sm(Zn_1/2Ti_1/2)O₃ ceramics sintered at 1310 °C for 2 h. For applications of high selective microwave ceramic resonator, filter and antenna, Sm(Zn_1/2Ti_1/2)O₃ is proposed as a suitable material candidate.
