Abstract
A system for growing an ingot from a melt includes an outer crucible, an inner crucible, and a weir. The outer crucible includes a first sidewall and a first base. The first sidewall and the first base define an outer cavity for containing the melt. The inner crucible is located within the outer cavity, and has a central longitudinal axis. The inner crucible includes a second sidewall and a second base having an opening therein. The opening in the second base is concentric with the central longitudinal axis. The weir is disposed between the outer crucible and the inner crucible for supporting the inner crucible.
