The usage of specific state of structural conponents of rare earth elements containing watersalt systems in preparation processes of the forming multicomponent oxide functional materials

Abstract

The preparatory processes phases of synthesis of REE multicomponent constructional and functional ceramic materials with rare earth elements (REE) with the use of salt systems of elements and with different electronic structures by chemical mixing of initial components with general product extraction from liquid phase with consecutive or joint deposition and next thermal processing occur through formation of a number of intermediate phases. The system investigation of chemical interaction of heterogeneous equilibriums in model systems there were found complex processes of interaction between their structural components as for formation of an integral class of anionic complexes Ln3+. The effective concurrent reactions are drastic processing factors essentially affecting activity of structural forms Ln3+.
