Abstract

[(Mg_1-xZn_x)_0.95Co_0.05]_1.02TiO_3.02ceramics were fabricated using solid-state synthesis for mobile communications. Zn²⁺and Co²⁺substitution enhanced the Qxf value and allowed densification sintering at lower temperature compared to that for [(Mg_1-xZn_x)_0.95Co_0.05]_1.02TiO_3.02, which must be sintered at 1175°C. [(Mg_0.6Zn_0.4)_0.95Co_0.05]_1.02TiO_3.02sintered at 1175°C has a dielectric constant of 20.1, a Qxf value of 280,000 GHz, and a τf value of -64.7ppm/° C. The maximum quality factor multiples resonant frequency (Qxf ) value of around 280,000GHz was obtained for the [(Mg_0.6Zn_0.4)_0.95Co_0.05]₂TiO₄.
