Comparison of Methods for Measurement of Curie Temperature
Original language description
The paper is focused on practical determination of piezoelectric materials’ behaviour at high temperatures near the Curie point. Temperature dependence of piezoelectric, elastic and dielectric coefficients near the Curie point is important yet hardly measurable material property of piezoelectric ceramics. Various methods can be used for measurement of temperature dependence of piezoelectric parameters and for the determination of the Curie point. Three methods have mostly been used for that purpose - a frequency method, X-ray diffraction spectroscopy (XRD) method and a thermal differential scanning calorimetry (DSC) analysis. These methods were also selected in this study, described in more detail and their results were compared with respect to achievable accuracy and requirements on instrumentation and preparation of samples. Cylinders of hard NCE41 and soft NCE55, NCE51 and PCM51 ceramics obtained from the company Noliac Ceramics were used for material coefficients temperature dependencies determin
