Description
Summary:Results of a thermodynamic and geometric-topological analysis of the subsolidus structure of the BaO - Al^sub 2^O^sub 3^ - Fe^sub 2^O^sub 3^ - SiO^sub 2^ system at temperatures above 1381 K are reported. Tetrahedratization of the system, with due regard for the existing high-temperature phases, is carried out. Data for solid-state reactions in the system obtained by thermodynamic and geometric-topological calculations are presented. Technological implications in the synthesis a new class of barium-containing cements with allowance for the specific subsolidus structure (associated with reversible solid-state reactions in ternary subsystems and the quaternary BaO - Al^sub 2^O^sub 3^ - Fe^sub 2^O^sub 3^ - SiO^sub 2^ system proper) are discussed.[PUBLICATION ABSTRACT]
