Two unusual, extensive new solid solutions of LiNbO{sub 3} and LiTaO{sub 3} with MnO have been prepared, where 4Mn{sup 2+} replace a combination of 3Li{sup +} and a pentavalent cation: Nb{sup 5+} or Ta{sup 5+}. The formulas are Li{sub 1{minus}x}M{sub 1{minus}x}Mn{sub 4x}O{sub 3}, 0 < x < 0.13, for M = Nb and 0 < x < 0.23 for M = Ta. The solid solutions were characterized by X-ray powder diffraction and density measurements. The manganese oxidation states were determined by X-ray photoelectron spectroscopy.
