N2 - The dielectric and structural characteristics of (Ca1-x Sr x)(Mg1/3Nb2/3)O3, (x= 0-0:5) solid solutions are investigated by measuring and observing these properties by X-ray diffractometry, transmission electron microscopy, and Raman spectroscopy. The splitting of superlattice reflections shows that the (Ca1-x Sr x)(Mg1/3Nb2/3)O3 solid solution has a 1 : 2 ordered structure distorted by the antiphase, the in-phase tilting of oxygen octahedra, and the antiparallel shift of cations at 0 - x - 0.5. The strontium substitution causes a tolerance factor increase, which leads to higher structure symmetry. This study indicates that ionic polarizability, tolerance factor, cation substitution, and grain size have a significant effect on the microwave dielectric properties of this solid solution.
