Stoichiography and chemical methods of phase analysis of multielement multiphase compounds and materials

Abstract

The problems and achievements in the determination of the phase composition of solid multielement multiphase inorganic compounds are considered. The problems of theory, methodology and practical use of two chemical methods of phase analysis, selective dissolution and standard-free stoichiographic dissolution are discussed. The unique potential of stoichiography and differentiating dissolution method, which allows one to overcome many limitations and difficulties typical of modern phase analysis techniques, are demonstrated. Examples of using differentiating dissolution for the phase analysis of diverse compounds and functional materials are given.
