英文摘要	A temperature stable high-Q Li2Zn0.95Sr0.05Ti3O8 microwave dielectric ceramic is fabricated by conventional solid-state reaction route and the phase composition, microstructures and microwave dielectric properties are investigated in this paper. The bulk density and FESEM results indicate that this ceramic can be well-sintered at 1075 degrees C for 4h. Since the difficulty in Sr2+ ions diffused into the Li2ZnTi3O8 crystal lattice to form solid solutions owing to the large radii difference between Sr2+ (1.44 angstrom) and Zn2+ (0.74 angstrom), there are three phases including the main phase Li2ZnTi3O8 and the second phase SrTiO3 and unknown phase according to the XRD and element-distribution mapping results. The formation of second phase is advantageous to improve the relative permittivity (epsilon(r)) and temperature coefficient of resonant frequency ((f)), but degrades the quality factor (Qxf) slightly. The Li2Zn0.95Sr0.05Ti3O8 ceramic sintered at 1075 degrees C/4h displays a temperature stable high-Q properties: epsilon(r)=26.6, Qxf=62300GHz, and (f)=0.27ppm/degrees C.
