Gallium oxide is an apparently simple oxide that has been reported to exist as at least 5 polymorphs all of which are stable at room temperature. Structural models, however, for most of these do not exist; this is despite their applications in, for example, catalysis. Some of these phases we suspect possess structural disorder and so to make a full characterisation of the phases, which we have successfully prepared, we will use total neutron scattering. Neutron (rather than X-ray scattering is highly desirable) because of the comparable scattering of oxygen to gallium and the high Q range obtainable at ISIS. This work forms part of larger project aimed at the structural characterisation of inorganic solids, including some structurally disordered phases.
