Formation of phases with the Ca₃Ga₂Ge₄O₁₄ structure in the AO-TeO₃-Ga₂O₃-XO₂ (A = Pb, Ba, Sr; X = Si, Ge) and PbO-TeO₃-MO-GeO₂ (M = Zn, Co) systems

Variable-composition phases with the Ca₃Ga₂Ge₄O₁₄ structure with a wide homogeneity region were synthesized in quaternary silicate and germanate systems. In (Pb,Ga)-containing systems, sections of the homogeneity region were studied and their boundaries were determined. Cationic vacancies were found...

Description
Summary:Variable-composition phases with the Ca₃Ga₂Ge₄O₁₄ structure with a wide homogeneity region were synthesized in quaternary silicate and germanate systems. In (Pb,Ga)-containing systems, sections of the homogeneity region were studied and their boundaries were determined. Cationic vacancies were found. In the 3e position, their concentration can be as high as 25%. The synthesized phases melt incongruently or experience solid-phase decomposition.
