BETA'-SNSB SINGLE-CRYSTALS OBTAINED BY THE METHOD OF INCLINED FRONT CRYSTALLIZATION

beta' phase plates of single crystals of SnSb alloy were obtained by using a modification of the horizontal Bridgman method. It was ascertained that during crystallization the single crystals grow in the upper layer of the charge. It was found that the thickness of the single crystal (single crystal layer) and also its relative antimony content, depend on the growth rate and on the angle of inclination of the crystallization front relative to the growth direction. A model proposed for the crystallization process permits the description of these relations obtained. This method for obtaining single crystals, the inclined front crystallization (IFC) method, offers new possibilities for control of chemical composition of plate single crystals of intermetallic phases, by varying the angle of inclination of the crystallization front.
