Low-loss dielectric ceramics based on Ba(B'Ta-1/2(1/2))O-3 (B'=La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Y, Yb, and In) complex perovskites have been prepared by the solid-state ceramic route. The dielectric properties (epsilon(r), ...

Sr(2)LnTaO(6) (Ln = lanthanides, Y, and In) ceramics were prepared by a solid-state route, and their vibrational phonon modes were investigated using Raman and infrared (IR) spectroscopic techniques. Lorentzian lines were ...

A(2)MgTeO(6) (A = Ba, Sr, Ca) ceramics were prepared by solid-state route and their microstructure and microwave dielectric properties, as well as the vibrational phonon modes were investigated using the resonance method ...
