Abstract:
The thermal transport properties, thermal diffusivity, thermal conductivity and specific heat
capacity of Dicalcium Lead Propionate (DLP) crystal have been measured following a modified
photopyroelectric thermal wave method. The measurements have been carried out with
thermal waves propagating along the three principal symmetry directions, so as to bring out the
anisotropy in these parameters. The variations of the above parameters through two prominent
phase transition temperatures of this crystal have also been measured to understand the variation
of these parameters as it undergoes ferroelectric phase transitions. In addition, complete
thermal analysis and FTIR measurements have been done on the crystal to bring out the correlation
of these results with the corresponding thermal transport properties. All these results are
presented and discussed. The data presented in this paper form a comprehensive set of results
on the thermal transport properties of this crystal.
