SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase transitions have received some attention - e.g. neutron diffraction at five distinct temperatures - and are reasonably well understood. These have been reviewed in the course of a recent dieletric and resonant ultrasound (RUS) study of SrAl2O4:Eu, and the need for more detailed experimental studies identified. The RUS shows a shear modulus inflection and strong dissipation and there is a weak dielectric anomaly, all at around 650 K, which does not coincide with any of the phase transitions previously reported. We plan to investigate these anomalies through a detailed study in fine temperature steps, obtaining precise strain and structural data, from room temperature through the phase transitons, to 1273 K.
