Abstract:
A device for loading raw material into a quartz crucible, which is used for loading polycrystalline silicon into a quartz crucible before manufacturing silicon single crystal by the CZ method, comprisinga container (3) having an inner diameter smaller than that of the quartz crucible (10);means (6) for loading polycrystalline silicon lumps (17) into the container (3);means (7) for pouring pure water into the container (3);means (8) for freezing the water poured into the container (3);means for taking out the ice block (22) made of polycrystalline silicon lumps (17) and pure water from the container (3) and loading it into the quartz crucible (10);means for melting the ice block (22) loaded into the quartz crucible (10); andmeans (13) for drying the quartz crucible (10) and polycrystalline silicon lumps (17) loaded thereinto.
