Аннотация: The behavior of wairakite CaAl2Si4O12 · 2H2O and dawsonite NaAlCO3(OH)2 in a water medium is studied by means of in situ Raman spectroscopy at the simultaneously high temperatures and pressures (up to T = 723 K and P = 1 GPa). After the initial minerals are partially dissolved, phillipsite forms in the wairakite–water system, and a glass-like phase is generated in the dawsonite–water system. These minerals show no signs of overhydration. The amorphization of the wairakite structure that occurs at high temperatures and pressures was reversible. © 2016, Allerton Press, Inc.
