Abstract

PURPOSE: To easily produce a high quality, long size single crystal without bending in pulling by gradually expanding the gap between the central position of the depth of a crucible and the central position of the length of a heater as a single crystal becomes longer by growing.
CONSTITUTION: A high m.p. oxide such as LiTaO3 is put into Pt-Rh crucible 3, RF coil 7 is electrified to melt the LiTaO3, and LiTaO3 single crystal 11 is pulled with seed crystal 10. As crystal 11 becomes longer, gap ΔH between central position H1/2 of coil 7 and central position H2/2 of crucible 3 is expanded gradually. At this time, it is required to grow crystal 11 while maintaining ΔH=-10W-50mm. As a result, by controlling convection currents in melt 8 of a proper temp. distribution, an oxide single crystal is obtd. without bending in pulling.
