An apparatus for growing a crystal includes a growth chamber and a melt chamber thermally isolated from the growth chamber. The growth chamber includes: a growth crucible configured to contain a liquid melt; and a die located in the growth crucible, the die having a die opening and one or more capillaries extending from within the growth crucible toward the die opening. The melt chamber includes: a melt crucible configured to receive feedstock material; and at least one heating element positioned within the melt chamber relative to the melt crucible to melt the feedstock material within the melt crucible to form the liquid melt. The apparatus also includes at least one capillary conveyor in fluid communication with the melt crucible and the growth crucible to transport the liquid melt from the melt crucible to the growth crucible.

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.
