Solid solutions of (1 − x)La(Co1/2Ti1/2)O3–xLa(Mg1/2Ti1/2)O3 were used to prepare La(Mg1−xCox)1/2Ti1/2O3 using solid-state synthesis. X-ray diffraction patterns of the sintered samples revealed single phase formation. A maximum density of 6.01 g/cm3 was obtained for La(Mg1−xCox)1/2Ti1/2O3 (x = 1) ceramics sintered at 1375 °C for 4 h. The maximum values of the dielectric constant (ɛr = 29.13) and the quality factor (Q × f = 80,000 GHz) were obtained for La(Mg1−xCox)1/2Ti1/2O3 with 1 wt% ZnO additive sintered at 1375 °C for 4 h. The temperature coefficient of resonant frequency τf was −59 ppm/°C for x = 0.3.
► La(Mg1−xCox)1/2Ti1/2O3 have been fabricated using solid state synthesis for mobile communications. ► ɛr value of 29.13, a Q × f value of 80000 (GHz) were obtained for La(Mg1−xCox)1/2Ti1/2O3(x=0.3) ceramics at 1375 °C for 4 h. ► No secondary phases can be observed in (1 − x)La(Co1/2Ti1/2)O3–xLa(Mg1/2Ti1/2)O3.
