摘要

PROBLEM TO BE SOLVED: To provide the method which enables improvement in yield of single crystal growth by preventing any damage to a seed crystal from being caused through reaction of a raw material before the crystal synthesis with the seed crystal and also to provide the device for the method. SOLUTION: This device is provided with a first vessel 8 for receiving a seed crystal 9 and growing a single crystal, a heating means 12 placed so as to encircle the first vessel 8; and a second vessel 3 that is placed above the first vessel 8 and has an opening 6 at the bottom and is used for receiving a raw material 4 for single crystal growth wherein the second vessel 3 is attachable and detachable and includes a sealing means 7 for sealing the opening 6.
