Effects of interaction in mixtures of ferroelectric powders C$_{6}$H$_{16}$NBr and PbTiO$_{3}$

The results of phase transitions studies in the mixture of C$_{6}$H$_{16}$NBr and PbTiO$_{3}$ powders and $x$PbTiO$_{3}$–$(1-x)$C$_{6}$H$_{16}$NBr composites for $x$ from 0.05 to 0.45 by the method of differential thermal analysis (DTA) are reported. A comparative analysis of the DTA signal and $\varepsilon'(T)$ composites $x$PbTiO$_{3}$–$(1-x)$C$_{6}$H$_{16}$NBr is presented. It was shown that the addition of lead titanate to C$_{6}$H$_{16}$NBr leads to the appearance of new phase transitions both in composites and in powder mixtures.
