Abstract:
Phase transitions in crystals of (Cs,NH$_{4})_{4}$(HSO$_{4}$)$_{3}$(H$_{2}$PO$_{4}$) 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 NH$_4$ in Cs$_{4}$(HSO$_{4})_{3}$(H$_{2}$PO$_{4}$) crystals reduces the temperatures of phase transformations.
Keywords:
superprotonic crystals, phase transitions, thermal properties, optical properties.
