Abstract
The mixed and impurity-added (doped) crystals of alkali halides are found to be harder than the end members and so they are more useful. In view of this, it becomes necessary and useful to prepare binary- and ternary-mixed crystals regardless of miscibility problem and characterize them by measuring their physical properties. In the present work, we have grown (KCl) x (KBr) y − x (KI) 1− y crystals for various values of x and y by the melt method and physically characterized. Bulk composition of the crystals was measured using the measured density and refractive index values. X-ray diffraction analysis indicates the existence of two phases in the mixed crystals. Thermal parameters were determined using the X-ray powder diffraction intensity data.
