Реферат:	eng: The thermophysical characteristics of the SrAlF5 crystal have been investigated on samples differing in quality. The results of studying the thermal expansion and birefringence in heating-cooling cycles in the temperature range of 100-800 K have been analyzed. Specific heat anomalies are found whose position on the temperature scale depends on the sample quality and thermal history. An X-ray diffraction analysis of SrAlF5 showed the absence of structural phase transitions in the temperature range under study. It is suggested that the specific heat anomalies are related to the peculiarity of transport properties of this crystal. © Pleiades Publishing, Inc., 2011.
