Abstract
Mixed crystals of alkali halides find their applications in optical, opto electronics and electronic devices. In the present study the pure and ZnO added mixed crystals KClx Br1-x were grown from the aqueous solution. The grown crystals were characterized by taking XRD, TG/DTA and Vickers microhardness measurement. The Debye temperature is an important parameter of a solid. Several methods of evaluating Debye temperature are available. In the present study Debye temperatures were calculated from the Debye-Waller factor, melting point and microhardness. The results were compared with the Kopp-Neumann relation.
