Abstract:
Based on the results of X-ray phase analysis and Mössbauer spectroscopy, it was demonstrated that in the ZrO$_2$–Fe$_2$O$_3$ system, represented by the mechanical mixture of $m$–ZrO$_2$ ($14\pm 2$ nm) and $\alpha$-Fe$_2$O$_2$ ($43\pm 2$ nm) nanoparticles, being heated above the temperature corresponding to the melting temperature of the two-dimensional nonautonomous phase, transformation of $\alpha$-Fe$_2$O$_2$ occurs resulting in appearing of the X-ray amorphous magnetically disordered state localized on the surface of ZrO$_2$ nanoparticles in the form of a thin layer. Transformation pattern in ZrO$_2$–Fe$_2$O$_3$ nanocrystalline system has been introduced.
