Popis:	This work presents X-ray diffraction results on the f - g first order phase transition in FePO 4 . An intermediate phase appears in a temperature range that corresponds to the excess of heat capacity previously attributed to a modulated phase. By means of Rietveld refinements structural parameters are obtained in all phases. In particular conclusions concerning the deformation of FeO 4 and PO 4 tetrahedra are driven.
