  • APPARATUS FOR THE PRODUCTION OF SILICON FROM MELT WITH INDICATION OF MELT SPILL AND MELT-SPILL ALARM SYSTEM
    Publication number: 20100061895
    Abstract: This invention relates to devices useful in the production of silicon from a melt. According to the invention there is provided an apparatus for the production of silicon from a melt with an indication of a melt spill, the apparatus comprising a crucible for producing a molten material, a susceptor for the crucible, and a melt-spill indicator comprising four leakage sensors. The susceptor for the crucible has four openings, each for accommodating a guiding rod, and each leakage sensor is composed of two electrodes, one of which being bowl-shaped and arranged under a respective guiding rod. The apparatus has a warning device for giving a warning of the melt spill. The apparatus of the invention provides for conditions of crystallization of polycrystalline silicon with any melt leakage adequately detected.
