The application of the general principles of the non-equilibrium thermodynamics and stoichiography allows obtaining novel information on the solid-phase transformations happening in multielement and heterophase substances and materials. Without the solid-phase standards, the use of stoichiography allows detecting, identifying and quantitative determining known and unknown crystalline and amorphous phases being of constant or variable composition. For the first time, reliable results concerning evolution of solid products during preparation of the Mo-V-Te-Nb-O catalyst of propane ammoxidation are presented.
