Cesium hafnium chloride (Cs2HfCl6) is considered due to its excellent scintillation properties as a promising candidate for cost effective radiation detectors. The Cs2HfCl6 is considered as relatively stable with low hygroscopicity, but still reaction with moisture when exposed to air atmosphere was reported. In this contribution we were focused on the preparation and crystal growth of Cs2HfCl6 by vertical Bridgman method. Samples of various dimensions were cut and polished for characterization of optical, luminescence, and scintillation properties, and their decay kinetics. Experiments of the Cs2HfCl6 stability and aging when exposed to ambient atmosphere were performed by measuring the weight change, absorption and radioluminescence spectra, and light yield.
