The present invention relates to compositions of matter represented by the general formula LnxLn'x'AyTizCe1-x-x'-y-zO2- delta wherein Ln is selected from the group consisting of Sm, Gd, Y, and mixtures thereof; Ln' is selected from the group consisting of La, Pr, Nd, Pm, Eu, Tb, Dy, Ho, Er, Tm, Yb, Lu, A is selected from the group consisting of Mg, Ca, Sr and Ba, 0.05 ≤ x ≤ 0.25, 0 ≤ x' ≤ 0.25, 0 ≤ y ≤ 0.03, 0.001 ≤ z ≤ 0.03, 0.05 ≤ x + x' ≤ 0.25, 0.001 ≤ y + z ≤ 0.03, wherein delta is a number which renders the composition of matter charge neutral. The compositions can be formed into sintered bodies suitable for use as solid electrolytes in devices including solid-state oxygen generators. Such sintered bodies have greater than 95% theoretical density at temperatures at or below 1600 DEG C, and can be produced by a solid-state method. |
