Abstract:
The results of the application of stoichiographic method of differential dissolution (DD) to analyze mixed
oxides with the perovskite-like structure are presented. The samples of Sr1Ti0.9Mg0.1O3 with the ABO3
stoichiometry of perovskite and samples of Sr2Ti0.9Mg0.1O4 with the A2BO4 stoichiometry of layered
perovskite (where A = Sr2+; B = Ti4+, Mg2+) are prepared by a mechanochemical method and analyzed
before and after catalytic tests. Conditions of the detection, identification, and quantitative determination of different phases in the compositions of the samples are described. The surface comppositions of the initial samples are determined by the DD method, and changes observed after the catalytic tests are noted. The DD results are compared with the powder XRD results.
