Summary

The nature and processes of decomposition of aluminium titanate (Al2TiO5) in vacuum from 20–1100°C have been characterized by time-of-flight neutron diffraction to study the temperature and time-dependent structural changes in real time during thermal decomposition. Results show that the thermal stability of Al2TiO5 in vacuum is strongly influenced by temperature, heating rates, phase purity, grain size, and additives. Possible mechanisms of structure stabilization or instability of Al2TiO5 under different conditions are discussed.
