Nonequilibrium Thermodynamics and Stoichiography in Studying Solid-Phase Processes of Fabrication of Functional Materials

Abstract

The application of general principles of nonequilibrium thermodynamics and stoichiography allows obtaining novel information on the solid-phase transformations of multielement and heterophase substances and materials. Without solid-phase standards, the use of stoichiography makes it possible to detect, identify, and quantify known and unknown crystalline and amorphous phases of constant or variable composition. For the first time, reliable results are presented concerning the evolution of solid products in the course of preparation of the Mo–V–Te–Nb–O catalyst of propane ammoxidation.
