摘要：
In this paper, the conditions of phase formation in the system CsOH-H2SO4-H3PO4-H2O are considered for the first time. The phase formation of Cs-6(SO4)(3)(H3PO4)(4) at t = 50 degrees C has been studied extensively. The main concentration boundary conditions for this compound are considered for the first time. The solubility congruence of Cs-6(SO4)(3)(H3PO4)(4) is shown. Conditions and approaches for obtaining crystals by isothermal evaporation and saturated solution temperature reduction methods are considered. The results of obtaining Cs-6(SO4)(3)(H3PO4)(4) crystals with maximum dimensions of similar to 20 mm are presented.
