LOCALIZED COOLING IN FLUX CRYSTAL GROWTH.

Abstract

Large crystals of a number of compounds have been grown from PbO-PbF2 flux systems utilizing a temperature gradient and localized cooling. The temperature gradient and localized cooling were induced by a jet of cold air directed on the crucible bottom. The temperature gradients of the crucible were measured and were found to be much less than the furnace temperature gradient. The technique is described, and a comparison is made of crystals grown with and without a temperature gradient. (Author)
