Complex investigations of the thermal stability as well as Mn-dopant distribution depending on chemical composition and processing condition have been performed in heavily doped SrTi1-xMnxO3 nanoparticles with x = 0.2 and 0.4. Prepared nanopowders reveal stable enough cubic perovskite structure even after treatment in oxidizing atmosphere up to 1000 degrees C. At the same time treatment in reducing atmosphere leads to decrease of the Mn solubility limit. Mn distribution evidences a weak tendency of Mn ions to migrate to surface. This migration increases in air and decreases at treatment in oxygen atmosphere. (C) 2016 Elsevier Ltd. All rights reserved.
