- Abstract
In this work, we calculated the thermodynamic characteristics of the reactions of SrAl2Si2O8 formation in the temperature range of 273–1573 K a) from starting oxides, b) from carbonate (or oxide) of strontium and initial Al2O3 and SiO2, c) from carbonate (or oxide) of strontium and metakaolin. The calculation of the heat capacity of SrAl2Si2O8 at 298 K was carried out by the incremental method of Kumok, Neumann-Kopp, Kubashevsky and group deposits. It is shown that it is thermodynamically most advantageous to carry out the solid-phase synthesis from SrO and Al2O3 2SiO2
