Abstract

PURPOSE: To obtaine the title single crystal for a jewel stable to the sunlight in a high yield by previously adding a predetermined amt. of one or more out of Ti, Zr, Hf and Th to a melt having a compsn. of Gd.Ga.garnet for pulling the single crystal.
CONSTITUTION: 6Wless than 80ppm of one or more out of Ti, Zr, Hf and Th are added to Ga.Gd.garnet (Gd3Ga5O12) pulverized and mixed. They are charged into an iridium crucible and melted in a high frequency furnace to grow a single crystal through a seed crystal by the Czochralski method as usual. Thus, a colorless transparent Gd.Ga.garnet single crystal is obtd. in a high yield, and this crystal has stable properties like diamond's and does not discolor even when exposed to the sunlight.
