Abstract
The crystal structure of Pb(ZrxTi1−x)O3 powders, 0.20≤x≤0.54, was determined using neutron diffraction measurements. At room temperature the structure was tetragonal (P4mm) for x≤0.50 and monoclinic (Cm) for 0.52≤x≤0.54. The sample having x=0.50 transformed from tetragonal symmetry to monoclinic at low temperature.
