Abstract
The domain structures of the beta-K2SO4 crystal were analyzed by group theo ry. We obtained the permissible kinds of domain association and domain wall s from the results of the group theory. It is suggested from the analysis t hat the (110) and (130) planes are W-mb walls. The value of the spontaneous strain of K2SO4 was epsilon = 6.32 x 10(-3) at room temperature and also i ts temperature dependence was observed.
