Description	The behaviour of material coefficients of PZT ceramics at temperatures approaching the Curie point is a problem hitherto not examined in detail. However, this field offers several interesting perspectives, such as the possibility of controlled depolarization of the piezoceramic material in the volume of a sample. The measurement of temperature dependences in piezoelectric materials used for sensors is very significant with respect to determining the degree of stability that characterizes the sensitivity and accuracy of a sensor; moreover, such measurement enables us to establish the maximum temperature ranges for regular operation. In the experiment described within the paper, we applied two temperature ranges according to the parameters of the calibration furnaces. While the first range spanned between -20 degC and 140 degC, the second one was defined by the boundary temperatures of 30 degC and 330 degC, where the latter value (330 degC) corresponds to the Curie point of the applied NCE 51 piezoelect The behaviour of material coefficients of PZT ceramics at temperatures approaching the Curie point is a problem hitherto not examined in detail.
