ABSTRACT:
Means for supplying raw material in additional charging or recharging of solid granular raw material into molten material in the crucible, comprises a raw material supply tube to be filled with said material, a metallic support member which runs through the inside of the tube, connects with the bottom lid, and serves for descending the lid and for ascending the tube and the lid, and a configuration avoiding metallic contamination, whereby the lower-end aperture of the tube is opened for charging said material therein into the crucible in uniform circumferential distribution and in large quantity, thus achieving efficient supply operation to be widely applied for growing silicon single crystals.
