Flow transitions in Czochralski oxide melts

The interface inversion observed in Gd3Ga5O12 and other oxide systems with the resulting wave formation in the molten oxide has been found to represent a form of baroclinic instability. With suitable modifications, the correlations developed for baroclinic instabilities in simulated meteorological systems can be applied to the Czochralski geometry. Furthermore, it has been found that the radial liquid temperature gradient in a RF Czochralski growth system is most strongly influenced by the crucible radius with the furnace insulation playing a secondary role.
