A process for the production of multicrystalline silicon ingots by the induction method comprises charging a silicon raw material into the melting chamber of a cooled crucible enveloped by an inductor  forming a melt surface  and melting  wherein the mass rate of charging the silicon raw material and the speed of pu...

This invention is related to obtaining multicrystalline silicon using induction method. The method comprises melting and casting of a pool in the form of a melting space, crystallization of a multicrystalline silicon ingot, and its controlled cooling by means of a heating equipment set. After the pool melting and ca...

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 ...
