A new thermally stable microwave dielectric ceramic with low-firing temperature in (1-x)Li3Bi2P3O12-xTiO(2) [(1-x)LBP-xT, 0 <= x <= 0.6] ceramics system was obtained using conventional solid-state reaction method. The phase transformation, microstructure, and microwave dielectric properties of materials were investigated using X-ray powder diffraction (XRD), scanning electron microscopy (SEM) , and a network analyzer. The LBP ceramic (x = 0) sintered at 725 degrees C has optimum microwave dielectric properties with relative permittivity (epsilon(r)) of 15.8, Q x f of 26 600 GHz and temperature coefficients of resonant frequency (tau(f)) of -130 ppm/degrees C. The epsilon(r) and tau(f) of (1-x)LBP-xT ceramics were tailored with increasing x values. At x = 0.55, the ceramic exhibits improved microwave dielectric properties with epsilon(r) = 22.1, Q x f = 14 900 GHz and tau(f) = -2.6 ppm/degrees C.
