Elastic compliance coefficients of K2SeO4 have been measured as functions of temperature by the composite-bar and piezoelectric resonance methods. The components s11, s22, s33 and s44 show anomalies around the transition temperature T2(129.5 K), but only s55 exhibits an anomaly at the Curie temperature T3 (93.0 K). The origin of these anomalies is qualitatively considered, taking into account the data of other experiments seen in literature.
