The domain structure appearing in ferroelastic LiKSO 4 at T < 190 K is analysed starting from the principle of macroscopic symmetry conservation. The transitions from, the point groups 6mm or 6 into mm2, 2, or 1 are considered in detail. It is shown that by the measurement of the split of reciprocal lattice node it is possible to determine the point group of the para‐ and ferroelastic phase in LiKSO 4 .
