Inorganic Materials Aims and scope

Abstract

Cs1 − x Rb x H2PO4 solid solutions have been synthesized for the first time in a broad composition range, x = 0.03–0.9. At room temperature, the Cs1 − x Rb x H2PO4 solid solutions are isostructural with the low-temperature phase of CsH2PO4 over the entire composition range studied. In the CsH2PO4-based solid-solution series, the unit-cell parameters and volume decrease with increasing Rb content. At high temperatures, the Cs1 − x Rb x H2PO4 solid solutions exist in the range x = 0–0.4, are isostructural with cubic CsH2PO4, and have a smaller unit-cell parameter.
