摘要：

The influence of crystal rotation rate and axial temperature gradient was investigated in the growth of high quality LiNbO3, Bi12GeO20 and Bi12SiO20 crystals. The meniscus weight in the withdrawal of the crystals was used as a tool to know the shape of the interface. This interface shape was simulated for different values of the rotation rate at a constant axial temperature gradient, and compared successfully with the experimental interface shape. The optimal experimental conditions to obtain a flat interface are discussed.
