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.
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 electrically connected to a warning device, and characterized in that the melt-spill indicator comprises four leakage sensors, the susceptor for the crucible comprises four side plates and a bottom plate having four openings, each of the side plates on the lower portion of the inner side thereof having a guiding face extending toward a respective opening via at least one groove, each opening accommodating a guiding rod, and each leakage sensor being composed of two electrodes, one of which being bowl-shaped and arranged under a respective guiding rod.
A melt-spill alarm system comprising a melt-spill indicator electrically connected to a warning device, and characterized in that the melt-spill indicator comprises four leakage sensors, each being composed of two electrodes, one of which being bowl-shaped for collecting any melt leakage and the other being electrically connected to the warning device.
