Abstract
Sr2La3Nb1−x Ta x Ti4O17 (0 ≤ x ≤ 1) ceramics were processed via a solid-state mixed oxide route. Sr2La3Nb1−x Ta x Ti4O17 (0 ≤ x ≤ 1) solid solutions were single phase in the whole range of x values within the x-ray diffraction (XRD) detection limit. The microstructure comprised elongated and needle-shaped grains. The ceramics exhibit relative permittivity (ε r) of 73 to 68.6, product of unloaded quality factor and resonant frequency (Q u f 0) of 7100 GHz to 9500 GHz, and temperature coefficient of resonant frequency (τ f) of 78.6 ppm/°C to 56.6 ppm/°C.
