Abstract

This paper summarizes data on new approaches to the detection, identification, and quantitative determination of manifestations of spatial inhomogeneities in the chemical composition and structure of mixtures of inorganic solid phases by a standardless differential dissolution (DD) stoichiographic method. We present mathematical modeling results for DD processes in different models for mixtures of solid phases. Based on the modeling results, we formulate rules of stoichiographic calculations for DD results, which are confirmed in identifying manifestations of spatial inhomogeneities in the phase composition of real systems, including fanlike separation of phase mixtures, without their selective separation.
