For barium cerate solid solutions BaCe${}_{1-x}$M${}_x$O${}_{3-\delta}$, realised by partial heterovalent substitution of Ce${}^{4+}$ ions by ions of yttrium and rare-earth metals (M — Pr${}^{3+}$, Nd${}^{3+}$, Sm${}^{3+}$, Gd${}^{3+}$) upon threating in air, the conditions for obtaining are studied. By the method of qualitative X-ray diffraction analysis, it was established that at a final synthesis temperature of 1373 K barium cerate compounds crystallize within the distorted perovskite-type structure. On the basis of X-ray diffraction analysis, parameters characterizing the structure of synthesized perovskite-like phases were determined. The ceramic properties (relative density, porosity, grain size) of the samples sintered at 1773 K were studied.
