Аннотация: In situ Raman spectroscopy is used to study the behavior of synthetic carbonate–aluminosilicate hydro-cancrinite Na6Ca2[(OH,CO3)2 Al6Si6O24]·2H2O compressed in an aqueous medium up to 1.6 GPa at 500°C. It is found that hydro-cancrinite retains its crystal structure up to 1.5 GPa and 300°C. It then amorphizes as the temperature rises, partially dissolves, and decomposes into two main products: nepheline and a scheelite-like compound.
