SOLID RAW MATERIAL SUPPLY DEVICE, MOLTEN RAW MATERIAL SUPPLY DEVICE, AND CRYSTAL PRODUCTION APPARATUS

摘要

A solid raw material input device that is capable of not only suppressing any splashing at inputting of an aggregated solid raw material in a crucible but also suppressing the scattering of any splash having occurred; and, including the solid raw material input device, a molten raw material supply device and crystal production apparatus. The solid raw material input device is solid raw material input device (10) comprising guide member (1) for guide and supply of aggregated solid raw material (4) to an opening of sub-crucible (21); solid raw material supply unit (3) for supply of the solid raw material (4) to the guide member (1); and scattering preventive member (2). Further, there are provided, including the solid raw material input device (10), molten raw material supply device (20,30) and crystal production apparatus (100).
