Abstract

Optical floating zone (OFZ) technique is one of the most used methods for growth of single crystals. Although OFZ has been extensively investigated for past decades, the temperature distribution during growth has not been understood due to the complicated process during growth. It makes the optimization of growth parameters very difficult. In this work, we presented a simplified model to calculate the temperature field in floating zone by FEM. The optical properties of grown crystal and ceramic perform rod, lamp power, filament dimensions, ceramic rod diameter, floating zone dimensions, and ambient gas cooling rate were considered in the model. The calculated results show good agreement with the experiments. The developed model opens up a new way to optimize the growth parameters for a variety of single crystals.
