The method for pulling large diameter single crystals with the abovesaid difficulties avoided is developed. Here the free melt surface does not depend on the growing crystal diameter and remains minimal during the whole growing process. The essence of this method is that at the stage of radial crystal growth the melt level in the crucible of a variable cross-section (for instance, in
