[en] Solid solutions of Nd_xY_1-xTiTaO₆ ceramics were prepared through the solid-state ceramic route. The structure of the system was analyzed by X-ray diffraction methods. The materials are sintered at 1560 deg. C and the sintered density increases with higher concentrations of Nd. The SEM images show the co-existence of two phases in the compositions x = 0.23-0.25. The dielectric constant (ε_r), temperature coefficient of resonant frequency (τ_f) and the unloaded quality factor (Q_u) are measured in the microwave frequency region using cavity resonator method. The dielectric constant increases with higher concentrations of Nd in the solid solutions. Nearly zero temperature coefficient of resonant frequency (τ_f) was obtained for Nd_0.24Y_0.76TiTaO₆. The samples are of high quality factor and are useful for practical applications
