<p>A system (18) for continuously supplying solid silicon particles to an apparatus (20) for growing hollow, tubular crystalline bodies. The system includes a container (70) for storing solid silicon particles (72), a vibratory, pneumatic, or other device for causing the particles to exit the container through an aperture (74) in the bottom thereof, a receiving chamber (82) coupled with the container for receiving the particles (72) which are dispensed from the container, and means (96) for providing a jet of pressurized fluid in the receiving chamber. The latter is coupled with the crucible of the crystal growth apparatus via a conduit (60) extending up through the center of the crucible. In operation, silicon particles (72) are dispensed from the container (70), travel into the receiving chamber (82) where they are entrained by the jet of pressurized fluid (96) which drives the particles out of the receiving chamber (82), through the conduit (60) and into the crystal growth furnace (20) where they fall back into the molten silicon supported in the crucible (24).</p> |
