The study of the thermal properties of condensed matter is very essential both for crystallizing and thermal energy induced fracturing of solid materials. Photoacoustic spectroscopy (PAS) is a recently developed, non-destructive testing (NDT) tool, used for analyzing the surface properties of materials. This method is used here to determine the thermal diffusivity and thermal conductivity of the gel grown single crystals of calcium carbonate (CC), which is the major constituent of pancreatic calculi. Characterization of CC was made using single crystal X-ray diffraction and density determination.
