摘要： A single-crystal growth apparatus includes: a raw-material accumulation tube housed in a pull chamber; a bottom lid attached to a lower end opening of the raw-material accumulation tube; a shaft connected to the bottom lid to lift/lower the accumulation tube and bottom lid; a forward/backward movable raw-material guide tube having a leading end to be inserted through a side wall of the pull chamber into the raw-material accumulation tube; and a raw-material supply apparatus for supplying solid raw materials through the raw-material guide tube into the raw-material accumulation tube, in which the solid raw materials are supplied from the raw-material supply apparatus, through the raw-material guide tube, to the raw-material accumulation tube with the leading end of the raw-material guide tube being inserted into the raw-material accumulation tube, so as to accumulate the solid raw materials, and the bottom lid is lowered to drop the solid raw materials into a crucible. Thus a large amount of raw-material melt can be formed efficiently in the crucible during growth of single crystal.
