- Аннотация: The kinetics and mechanism of corundum formation from hydrargillite in an aqueous medium under sub and supercritical conditions in the presence of manganese ions was studied. The conclusion was drawn that corundum structure formation with the insertion and uniform distribution of manganese ions occurred thanks to solidstate mobility, which appeared under the conditions of reversible dehydroxylation in the interaction of a solid matrix with an aqueous fluid. Complex defects containing Mn2+, Mn3+, and Mn4+ ions along with hydroxyl groups and oxygen vacancies were formed when corundum was doped with manganese ions in different charge states because of redox processes in a supercritical aqueous fluid. Corundum doped with manganese exhibited ferromagnetic properties at room temperature.
