The activation temperature of the BiFeO3 nucleation and nanocrystal growth is shown to correlate with that of the nonautonomous phase’s melting. The optimal temperature range during nanoparticle formation by the method in question was found to be between 460–520(40) оC.</p></abstract><kwd-group xml:lang="en"><kwd>nanoparticles</kwd><kwd>multiferroics</kwd><kwd>bismuth ferrite</kwd><kwd>hightemperature Xray diffractometry</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The reported study was partially supported by RFBR, research project No. 120831453 mol_a</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">G.A.
