    Abstract: Embodiments of a reflective surface and a reflector comprising a reflective surface for use in a thermal decomposition reactor are disclosed. Methods for using the reflective surface, or reflector comprising the reflective surface, to manage a temperature profile in a silicon rod grown in the thermal decomposition reactor are also disclosed. The reflective surface is configured to receive radiant heat energy emitted from an energy emitting region of an elongated polysilicon body grown during chemical vapor deposition onto a silicon filament and reflect at least a portion of the received radiant heat energy to a reflected energy receiving region of the elongated polysilicon body or to a reflected energy receiving region of a second elongated polysilicon body, to thereby add radiant heat energy to the reflected energy receiving region.

    Abstract: Reaction chamber liners for use in a fluidized bed reactor for production of polysilicon-coated granulate material are disclosed. The liners include an aperture and a cavity configured to receive a reactor component, such as a probe, a sensor, a nozzle, a feed line, a sampling line, a heating/cooling component, or the like. In some embodiments, the liner is a segmented liner comprised of vertically stacked or laterally joined segments, wherein at least one segment includes an aperture and a cavity configured to receive a reactor component.

    Abstract: Methods and apparatus for separating polysilicon powder from a mixture of granular polysilicon and polysilicon powder are disclosed. The method includes tumbling the polysilicon material in a tumbling device. The tumbling device includes a tumbler drum having one or more lifting vanes spaced apart from one another and extending longitudinally along an interior surface of the tumbler drum. The lifting vanes facilitate separation of polysilicon powder and granules as the tumbler drum is rotated about its longitudinal axis of rotation.

    Abstract: This disclosure concerns embodiments of an annealing device and a method for annealing granular silicon to reduce a hydrogen content of the granular silicon. The annealing device comprises at least one tube through which granular silicon is flowed downwardly. The tube includes a heating zone and (i) a residence zone below the heating zone, (ii) a cooling zone below the heating zone, or (iii) a residence zone below the heating zone and a cooling zone below the residence zone. An inert gas is flowed upwardly through the tube. The tube may be constructed from two or more tube segments. The annealing device may include a plurality of tubes arranged in parallel and housed within a shell. The annealing device and method are suitable for a continuous process.

    Abstract: An oscillatory feeder operable to convey a flowable solid material has a tubular body and a displaceable body segment. The tubular body has at least one first end, at least one second end opposite the first end and a displaceable body segment between the first and second ends. The displaceable body segment has a first fixable location positionable at a first fixed location and a second fixable location positionable at a second fixed location. The actuator is attached to the displaceable body segment and controllable to cause selected displacement of the body segment and attached actuator and corresponding selected flow of solid material within the displaceable body segment in a feed direction extending generally from the first end to the second end.
