Single crystals of ZCTC with dimension up to 5x2x3mm3 were grown from aqueous solution by slow solvent evaporation method and the grown crystals were confirmed by single XRD and CHN analysis. The SHG efficiency of ZCTC was evaluated using Kurtz Perry technique. Its efficiency was found to be nearly 12 times that of urea when studied with the fundamental wavelength of 1064 nm. The mechanical properties of the grown crystal have been investigated by Vickers microhardness testing. The thermal parameters such as the thermal diffusivity, thermal effusivity, thermal conductivity and heat capacity of ZCTC were measured by an improved photopyroelectric (PPE) technique and the results were discussed. The TG/DTG studies reveal that the decomposition of the sample begins around 350°C. The photoconducting nature of ZCTC has also been investigated and reported.
