Abstract: Phase relations in the subsolidus region are considered for 54 ternary systems including M₂O₃–V₂O₅–R₂O₅, Y₂O₃ (La₂O₃, Sc₂O₃)–Nb₂O₅–Ta₂O₅, M₂O₃–B₂O₃–R₂O₅, M₂O₃–Ga₂O₃–R₂O₅, Al₂O₃–V₂O₅–R₂O₅ (where M is a rare-earth element and R = Ta, Nb). The criteria determining the formation of ternary oxide compounds were found to include the cation sizes and the ratios between the radii of the ions constituting the anionic part of the compounds. The crystal-chemical characteristics are presented for MR₂VO₉, LaRB₂O₇, La₄VBO₁₀, Ln₇VBO₁₇ (Ln = La, Pr, Nd), La₃Ga_5.5R_0.5O₁₄. The vibrational spectra of polycrystals of ternary compounds and solid solutions based on them are described in detail. The bibliography includes 154 references.
