AbstractNovel microwave dielectric ceramic Y3ZnAl3SiO12were synthesized by solid-state route. The crystal structure of synthesized samples was characterized by X-ray diffraction and refined with Rietveld method. Microstructure and microwave dielectric properties of Y3ZnAl3SiO12ceramics were investigated using Scanning Electron Microscopy and Hakki–Coleman method. X-ray data display that major phase of Y3ZnAl3SiO12is isostructural to Y3Al5O12with a cubic garnet structure and space group of Ia-3d, which is composed of (Al/Si)O4tetrahedron, (Zn/Al)O6octahedron and YO8dodecahedron, besides minor Y2SiO5secondary phase. The distribution of grain sizes is closer to Gauss distribution. Bulk density of samples has a similar variation curve with Q*f of samples. Y3ZnAl3SiO12ceramics exhibit excellent microwave dielectric properties: Εr= 10.2, Q*f = 37938.2 (@9.47 GHz), τf= −31.7 ppm/°C at sintering temperature of 1500 °C. Our results indicate Y3ZnAl3SiO12could be a potential material for millimeter wave communication systems as microwave substrates. © 2017, Springer Science+Business Media, LLC.
