Abstract

PURPOSE:In heat treating the single crystal of an oxide obtained by the pulling up method at high temperatures, to fill a space between a vessel accommodating a single crystal mass and the contact surface of the single crystal with the powder of said single crystal to create uniform heat distribution and stress distribution states, thereby preventing the occurrence of cracks.
