Prediction of the equilibrium composition of the products of high-temperature interaction in complex oxide systems

A thermodynamic analysis of parallel-sequential reactions taking place in complex oxide systems has been carried out. The use of the Karapetyants technique with the involvement of the improved Hook-Jeeves method made it possible to determine the optimal area of ??the investigated compositions and the most rational temperature range for heat treatment of coatings. This made it possible to significantly reduce the subsequent experimental part of the work and reduce it to checking the optimum found thermodynamically. Tab. 2, ill. 4, bibliography: 4 titles.
