| 英文摘要 | The Y3MgAl3SiO12 ceramics with pure phase were successfully synthesized by solid-state sintering reaction method for the first time. Their microwave dielectric properties were investigated as a function of sintering temperature. Their microstructure characteristics and ionic occupation sites of tetrahedral and octahedral units were characterized and analyzed by SEM& energy dispersive spectrometer (EDS) and Rietveld refinement of X-ray powder diffraction data. Crystal structure of Y3MgAl3SiO12 is isostructural to Y3Al5O12 with a cubic garnet structure and space group of Ia-3d, which contains YO8 dodecahedra, (Mg/Al-oct)O-6 octahedral, and (Si/Al-tet)O-4 tetrahedral units. The Qf and epsilon(r) values of different samples are strongly dependent on the distribution of grain sizes, grain sizes, and porosity. The samples sintered at 1550 degrees C exhibit optimized microwave dielectric properties with relative permittivity (epsilon(r)) of 10.1, Qf values of 57 340GHz (at 9.5 GHz), and tau(f) values of -32 ppm/degrees C. Such properties indicate potential application of Y3MgAl3SiO12 as microwave substrates. |
