Large crystals of ZnO, Al 2 O 3 , Ga 2 O 3 , ThO 2 , Y 3 Ga 5 O 12 , ZnGa 2 O 4 , and ZrO 2 were grown from PbO‐PbF 2 flux systems using a temperature gradient and localized cooling induced by a jet of cold air directed on the crucible bottom. The temperature gradients in the crucible were much less than that in the furnace. The technique is described, and crystals grown with and without a temperature gradient are compared.
