| Description | Journal: Journal of Physics C: Solid State Physics An attempt is made to explain the first-order phase transition (180.4 degrees C) and the presence of an intermediate phase (180.4 degrees C-300 degrees C) between the para- and ferro-phases in lead phosphate, $Pb_{3}(PO_{4})_{2}$, by invoking the basic ideas of the three-dimensional renormalised Potts model. This involves the introduction of three order parameters with two different critical temperatures. A relaxational type flip mode is proposed as the driving soft mode. The abnormal behaviour of the spontaneous strain between 160 degrees C and 180 degrees C, as well as the anomalous behaviour of the elastic stiffness constants $C_{11}$ and $C_{22}$ during the phase transition, are explained. |
