Resumo

Crystals of a series of solid solutions (KxRb1–x)9H7(SO4)8·H2O have been studied, and the extreme member of the series Rb9H7(SO4)8·H2O apparently does not exist under normal conditions. Solid solutions are limited by the composition x = 0.19, which corresponds to 81% rubidium content in the cationic composition. The lattice parameters of solid solutions have been determined, thermal properties and dehydration processes of crystallization water for both single-crystal and polycrystalline samples have been studied. The conductivity of samples with the maximum rubidium content has been investigated. It has been shown that the mechanism of occurrence of the state with high conductivity in solid solutions is similar to that in K9H7(SO4)8·H2O and is related to the dehydration process and stabilization of the dehydrated structure.
