Abstract: Systems and methods for forming an ingot from a melt are disclosed. A system includes a crucible defining a cavity for receiving the melt, and a first and second barrier to inhibit movement of the melt. A first passageway and a second passageway are arranged to allow the melt located within an outer zone to move into and through a transition zone and into an inner zone. Conditioning members are placed in at least one of the zones and arranged to contact the melt to reduce the number of micro-voids in the melt.
