    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: Apparatus and methods for consolidating granular silicon and determining trace elements content of the consolidated silicon are disclosed. Silicon granules are placed in a vessel, and a silicon slug of known purity is embedded at least partially in the granules. The slug is preheated to a temperature sufficient to couple with an induction heater. As the silicon slug melts, silicon granules adjacent the molten silicon also melt. The vessel passes through an induction coil to successively inductively heat and melt regions of the silicon granules from the leading end to the trailing end with each region solidifying as the molten silicon exits the induction coil to provide a multicrystalline silicon ingot. The multicrystalline silicon ingot is sliced into wafers, which are analyzed by low-temperature Fourier transform infrared spectroscopy to determine levels of trace elements in the ingot.

    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.
