  • Apparatus for producing multicrystalline silicon ingots by induction method
    Patent number: 9039835
    Abstract: An apparatus for producing multicrystalline silicon ingots by the induction method comprises an enclosure, which includes means for start-up heating of silicon and a cooled crucible enveloped by an inductor. The crucible has a movable bottom and four walls consisting of sections spaced apart by vertically extending slots, means for moving the movable bottom, and a controlled cooling compartment arranged under the cooled crucible. The inside face of the crucible defines a melting chamber of a rectangular or square cross-section. The walls of the cooled crucible extend outwards at least from the inductor toward the lowest portion of the cooled crucible to thereby expand the melting chamber, and the angle ? of expanding the melting chamber is defined by the equation ?=arctg[2·(k?1.
