Abstract

PURPOSE: To enhance the single crystallization rate and the homogeneity of a single crystal by coating the tip of a crucible and the small tube holding a seed crystal with a heat-resistant heat-insulating material when a single crystal is manufactured by the Bridgmen method using the seed crystal.
CONSTITUTION: A cylindrical crucible 1 having a small tube 3 holding a seed crystal at the tip part 2 is used. A seed crystal 4 having an arbitray crystal axis is inserted in the tube 3, and the body 1 and the tip part 2 are packed with starting material 5. All of the material 5 and part of the crystal 4 are melted to grow a crystal from the crystal 4 toward the tip part 2 and the body 1. Thus, a single crystal is manufactured. At this time, the tip part 2 and the tube 3 are coated with a heat- resistant heat-insulating material 6 such as alumina, and the opening angle α of the tip part 2 is preferably adjusted to ≥30°. As a result, the temp. difference between the central part of the crucible 1 and a part close to the wall is reduced, and the formation of a crystal nucleus differnet from the seed crystal is prevented.
