Crystal structure oj' intermediate phase of PbZr0, was analyzed by neutronpowder diffraction. St?perlattice reflections of our sample appeared at M and Rpoints. Intensities of fundamental reflections also changed in the phase. The structural modulations werc: associated with modes either U.,-VM.-FR., or F.,-FM;-1-R.,.The modulation associated with the 7?., mode of our sample might be caused by an extrinsic origin. Dielectric constant was also measured and a mechanism of the phasetransitions is discussed briefly.crystal structure, fe?=roelectrics, lead zirconate, Rietveld analysis
