• The dielectric properties of TlH2AS0. powder pellet are investigated over the tem-perature range from 80 to 433 K. With respect to the form of the temperaturedependence of complex dielectric constant, TlH.As0. crystal shows much the samecharacteristics as with the TlH2P0. crystal. The results are indicative of a first-orderantiferroelectric phase transition at 250.5 K (the lower phase transition point, 7'.)with thermal hysteresis of 1.4 K, and of a second-order ferroelastic phase transitionat about 390 K (the upper phase transition point, 7'.).
