N2 - © 2015, Allerton Press, Inc.The results from investigations of the acoustic properties of NaBi(MoO4)2 and NaBi(WO4)2 crystals above room temperature are presented. Variations in ultrasound velocity that indicate the occurrence of phase transitions are observed. Phase transitions for NaBi(MoO4)2 and NaBi(WO4)2 crystals are observed near 309 and 319 K, respectively. It is assumed that these phase transitions are associated with the ordering of Na+ and Bi3+ ions over cation sites. Observed anomalies in elastic properties and sound attenuation allow an interpretation based on the phenomenological Landau theory.
