The temperature-dependent components of the anisotropic thermal diffusivity of lead iodide (PbI2) have been measured by Laser Flash Analysis (LFA). The temperature range used was -100 degrees C to +350 degrees C. The temperature-dependent specific heat capacity c(p) was determined independently by Differential Scanning Calorimetry (DSC) to calculate the thermal conductivities for PbI2 from the thermal diffusivity data. At 27 degrees C, the thermal conductivity in the c-axis-direction, k(33), is 0.315 W m(-1) K-1, whereas the component perpendicular to the c-axis, k(11), is 0.681 W m(-1) K-1. The anisotropy ratio k(33)/k(11) changes from 1:2 at -100 degrees C to 1:2.4 at +350 degrees C. The temperature dependencies of both k(33) and k(11) in this range can be very well fitted with 3rd order polynomials. (C) 2017 Elsevier B.V. All rights reserved.
