Abstract

Sr _{2− x} Ca _x MgTeO ₆ (0 ≤ x ≤ 2) ceramics were prepared by the solid-state ceramic route. Structure and microstructure of the compounds were investigated using XRD, TEM, and SEM methods. The system undergoes a transition from pseudocubic tetragonal I 4/ m symmetry for x = 0 (Sr ₂ MgTeO ₆ ) to pseudotetragonal monoclinic P 2 ₁ /n symmetry for x > 0. The dielectric properties of the ceramics were studied by the resonance method. The temperature coefficient of resonant frequency is negative throughout the series; permittivities were in the range 13.2−14.3, and quality factors varied from 27500 to 81000 (5−6 GHz).
