Abstract
The influence of crystal rotation rate and axial temperature gradient was investigated in the growth of high quality LiNbO3, Bi12GeO20 and B i12SiO20 crystals. The meniscus weight in the withdrawal of the crysta ls was used as a tool to know the shape of the interface. This interfa ce shape was simulated for different values of the rotation rate at a constant axial temperature gradient, and compared successfully with th e experimental interface shape. The optimal experimental conditions to obtain a flat interface are discussed.
