Phase equilibria in three quinary systems of Li, Na, K, Sr//Cl-H2O at 25 degrees C, Li, Na, K//SO4, B4O7-H2O at 0 degrees C, and Na, K, Mg//SO4, B4O7-H2O at 15 degrees C were investigated by means of translation method. The quinary invariant points, monovariant curves, divariant fields, and trivariant volumes which are saturated with four, three, two, and one solid phases with relevant equilibrium liquid phases, respectively, were determined in each of the systems. Two points, seven curves, and nine fields were determined in the Li, Na, K, Sr//Cl-H2O system at 25 degrees C. Six points, 18 curves, and 19 fields were found in the Li, Na, K//SO4, B4O7-H2O system at 0 degrees C. Seven points, 20 one curves, and 20 two fields were determined in the Na, K, Mg//SO4, B4O7-H2O system at 15 degrees C on the quinary level. The total phase equilibria diagrams of each of the systems were constructed. The constructed diagrams were fragmented into trivariant crystallization volumes of equilibrium solid phases. The obtained volumes reflected the structures of projected diagrams of systems saturated with relevant equilibrium solid phases and involved the recent experimental results on KCl, Li2B4O7 along with Na2B4O7, and MgB4O7 center dot 9H(2)O saturated parts of the quinary systems: Li, Na, K, Sr//Cl-H2O at 25 degrees C, Li, Na, K//SO4, B4O7-H2O at 0 degrees C, and Na, K, Mg//SO4, B4O7-H2O at 15 degrees C, respectively. The obtained results clarified the reciprocal relations of phase conglomerates in the systems comprehensively.
