Abstract

A new temperature stable microwave dielectric with low-firing temperature in xBi₂MoO₆-(1 - x)TiO₂ system was prepared by conventional solid state reaction method. The crystalline phases, sintering behavior, microwave dielectric properties of xBi₂MoO₆-(1 - x)TiO₂ ceramics were studied. All the xBi₂MoO₆-(1 - x)TiO₂ ceramics could be well sintered at 850 °C for 3 h. X-ray diffraction analysis showed that tetragonal rutile phase and monoclinic Bi₂MoO₆ phase coexisted in the ceramic. The permittivity ε_r changed from 77.5 to 33.5 and the temperature coefficient of resonant frequency τ_f value shifted from +348.1 to -37.8 ppm/°C as the x value increased from 0.06 to 0.65. The temperature stable microwave dielectric ceramic was obtained when x = 0.57 in the xBi₂MoO₆-(1 - x)TiO₂ system, and it showed excellent dielectric properties of ε_r = 36.7, Qf = 16,800 GHz and τ_f = 0 ppm/°C.
