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.

Abstract: A system for growing silicon crystal structures includes a housing defining a growth chamber and a feed system connected to the housing for delivering silicon particles to the growth chamber. The feed system includes a container for holding the silicon particles. The container includes an outlet for discharging the silicon particles. The feed system also includes a channel connected to the outlet such that silicon particles discharged from the container flow through the channel. The feed system further includes a separation valve connected to the channel and to the housing. The separation valve is configured such that a portion of the feed system rotates relative to the housing.
