The ferroelastic domain pattern observed in Pb 3 (PO 4 ) 2 at room temperature is analysed in terms of twinning by pseudosymmetry. The characteristics of the three kinds of domains and the two types ( W and W ′) of walls are determined and agree with the experimental observations. The variation with temperature of the spontaneous strain is deduced from the investigation of the orientation of W ′ walls.
