Abstract
The solubility in the CsH2PO4‒CsHSO4‒H2O system at different temperatures (25, 50, and 75°C) is studied and the phase equilibria in the Rb3H(SO4)2‒RbH2PO4‒H2O system under isothermal conditions (at 25°C) are analyzed. The temperature and concentration conditions for forming Rb2(HSO4)(H2PO4), Rb4(HSO4)3(H2PO4), Cs4(HSO4)3(H2PO4), Cs3(HSO4)2(H2PO4), Cs2(HSO4)(H2PO4), and Cs6H(HSO4)3(H2PO4)4 compounds (the latter has been obtained for the first time) are determined. The conditions for growing large single crystals of complex acid rubidium and cesium salts are found.
