The mechanism of BiFeO3 nanoparticle formation from initial compositions obtained by bismuth and iron hydroxides coprecipitation has been studied. 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) °C.
Keywords: nanoparticles, multiferroics, bismuth ferrite, hightemperature X-ray diffractometry.
