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

beta' phase plates of single crystals of SnSb alloy were obtained by u sing a modification of the horizontal Bridgman method. It was ascertai ned that during crystallization the single crystals grow in the upper layer of the charge. It was found that the thickness of the single cry stal (single crystal layer) and also its relative antimony content, de pend on the growth rate and on the angle of inclination of the crystal lization 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 fro nt crystallization (IFC) method, offers new possibilities for control of chemical composition of plate single crystals of intermetallic phas es, by varying the angle of inclination of the crystallization front.
