Synthesis, Structure and Electrophysical Properties of Fluoride-Conducting Phases Вa1-XLaXSnF4+X
It has been determined that the concentration interval for the existence of solid solutions of heterovalent substitution Ba1−xLaxSnF4+x, which are formed by the partial replacement of barium cations with lanthanum cations in the BaSnF4 compound, is 0.0<x≤0.12. The obtained phases are isostructural BaSnF4, have a crystal lattice of tetragonal syngony, corresponding to the P4/nmm space group.
