Dielectric Properties of Low-sintering-temperature Bi12CeO20–BiFeO3 Ceramics at Microwave Frequency

BiFeO 3 ceramic, antenna temperature sensorIn this study, we prepared (1 -x)Bi 12 CeO 20 -xBiFeO 3 ceramics using conventional solid-state methods with various material compositions and sintering temperatures.X-ray diffraction and scanning electron microscopy were employed to analyze the composition of the ceramic microstructures.In experiments, as x increased, the dielectric constant and τ f value increased, and the Q × f value decreased.We also investigated the correlation between the relative proportions of two ceramic substances and their microwave dielectric properties.The Bi 12 CeO 20 -BiFeO 3 ceramic system is suitable for use as a substrate in low-temperature cofired ceramic antenna temperature sensors.
