Characteristics of surface acoustic waves (SAW) on fresnoite (Ba2Si2TiO8) single crystals are calculated using published and recently measured data. It is found that Ba2Si2TiO8is located between LiNbO3and LiTaO3in the SAW characteristics. No sets of temperature‐compensated propagation planes and directions are found among major singly rotated cuts in Ba2Si2TiO8.
