Abstract
PURPOSE: To effect a high-yield growing of a good quality lead molybdate using a Czochralski method by lowering a high-frequency heat source at a speed lower than that of the molten surface of lead molybdate.
CONSTITUTION: A lead molybdate powder material is placed in a noble metal crucible and melted with a high-frequency heat source installed around the crucible. A Czochralski method is used so that a seed crystal is brought into contact with the molten liquid and is pulled to produce a single crystal of lead molybdate. In this process, the high-frequency heat source may be lowered at a speed 15W25% of that at which the molten surface of the lead molybdate is lowered or the temperature of the noble metal crucible may be raised.
