ZrWMoO8 has been shown to undergo a phase transition at remarkably low temperatures in which oxygen atoms become dynamically disordered. The kinetics of this process have been studied by a variety of laboratory-based time and temperature dependent powder diffraction experiments. Oxygen mobility from temperatures as low as 205 K has been confirmed and an activation energy of 34 kJ mol−1 estimated for the migration process.
