The Chemistry of Spinel Ferrite Nanoparticle Nucleation, Crystallization, and Growth.

ABSTRACT: The nucleation, crystallization, and growth mechanisms of MnFe₂O_4, CoFe₂O₄, NiFe₂O₄, and ZnFe₂O₄ nanocrystallites prepared from coprecipitated transition metal (TM) hydroxide precursors treated at sub-, near-, and supercritical hydrothermal conditions have been studied by in situ X-ray total scattering (TS) with pair distribution function (PDF) analysis, and in situ synchrotron powder X-ray diffraction (PXRD) with Rietveld analysis. The in situ TS experiments were carried out on 0.6 M TM hydroxide precursors prepared from aqueous metal chloride solutions using 24.5% NH₄OH as the precipitating base. The PDF analysis reveals equivalent nucleation processes for the four spin
