Abstract
X-ray diffraction studies of a dilute BaTi0.97Zr0.03O3 ferroelectric a re discussed. It is shown that, at 117 degrees C, the sample undergoes a smooth ferroelectric phase transition from a cubic to a tetragonal phase. The temperature variations of the parameters characterizing the shape of X-ray powder reflections were investigated in the temperatur e range 60-300 degrees C. Based on these variations, the following seq uence of phases was determined: a cubic paraelectric phase (above 135 degrees C), a dipole glass (117-135 degrees C), a mixed phase (100-117 degrees C), and a tetragonal ferroelectric phase (below 100 degrees C ).
