The purpose of the work was to reveal the regularities of the formation and growth of mixed alkali-halide crystals from KCl–KBr–H2O solutions, the peculiarities of their structure, as well as the changes in the properties under the effect of X-radiation.
It is established that the effect of X-radiation leads to the increase of the rate of mixed crystals growth on the first and the last stages of growth (20-30%). Thus, the X-radiation contributes to the inclusion of less electronegative components into the crystal lattice of a solid solution.
By means of X-ray diffraction analysis it has been found that the effect of X-radiation on the formation and growth of mixed crystals leads to the formation of crystals with a not uniform, level by level microstructure. Thus, the X-radiation promotes enrichment of external and internal zones of growing crystals with less electronegative components, that results in increase of growing mass rate of a crystal.
