Abstract
Solid solutions Cs3 – 2x M x PO4 (M = Ba, Sr, Ca, Mg) are synthesized and their thermal behavior and electroconductivity are examined. Adding elements of Subgroup IIA of the periodic table into cesium orthophosphate shifts the phase transition, which occurs in pure Cs3PO4 at 450–620°С, towards lower temperatures and raises the cesium cation conductivity at low temperatures. The electroconductivity of a high-temperature modification of Cs3PO4 is weakly dependent on the presence and concentration of such additives, which points to structural disordering of the cesium sublattice.
