Resumo

Phase transitions in crystals of (Cs,NH₄)₄(HSO₄)₃(H₂PO₄) solid solutions have been investigated by synchronous thermal analysis and polarization microscopy at different temperatures. The temperatures of structural modifications are established; it is shown that the replacement of Cs cations with NH₄ in Cs₄(HSO₄)₃(H₂PO₄) crystals reduces the temperatures of phase transformations.
