The sintering behaviour and microwave dielectric properties of LiCaPO4 ceramic synthesized by the solid-state reaction method have been investigated, and the vibration property has been discussed with the help of the first principle calculation. Characterisation methods include X-ray diffraction, scanning electron microscopy, network analysis, differentia-thermal and thermo-mechanical analysis, and Raman spectrometry. The increasing sintering temperature results in the formation of the second phase. The composite ceramic with two phases (LiCaPO4 and Ca3(PO4)2) has formed when sintered at 950 °C, 2.99 g/cm3 for density, 20.09 for ɛr and tanδ = 0.008 at 8 GHz.
