Abstract
PURPOSE: To enhance the reproducibility of single crystal producing conditions by solidifying a residual melt in a crucible from the crucible bottom to prevent deformation of the crucible by shifting the relative position between the crucible and a work coil.
CONSTITUTION: A sintered body of LiTaO3 or the like is put into crucible 1 and heat melted with a heater such as work coil 5. After pulling a single crystal with a seed crystal, residual solidified crystal 2 in crucible 1 is supplied with sintered LiTaO3 and heat melted to form a single crystal again. Coil 5 is then heightened relatively to crucible 1 to raise the temp. of the upper part of crucible 1, thereby solidifying the residual melt in crucible 1 from the crucible bottom. By this method deformation of crucible 1 is reduced to elongate the service life. Accordingly, changes in crystal growing conditions are minimized, and crystals are produced with high reproducibility.
