Resumo

The phase equilibria in the quaternary water–salt system Cs₂SO₄–Rb₂SO₄–H₂SO₄–H₂O have been studied. The crystallization ranges are determined, and single crystals of (Cs_1 – _xRb_x)₂SO₄ and Cs_1 – _xRb_xHSO₄ solid solutions have been grown. The (Cs_1 – _xRb_x)₃H(SO₄)₂ and (Cs_1 – _xRb_x)₅H₃(SO₄)₄ · yH₂O compounds are obtained for the first time.
