Since the first report in 2015, High Entropy Oxides (HEOs) have gained interest from a variety of fields as they provide an expanded compositional space with opportunities for designing novel materials and tuning their properties. In order to compare synthesis methods and gain insight in the kinetics involved, we have employed rapid in-situ non-ambient X-ray diffraction to characterize the phase transformation and evolution of crystallinity in HEO materials synthesized via both the solid-state method and polymeric steric entrapment. From these studies the transformation behavior and kinetic behavior are revealed and discussed as function of composition and processing method.
