    Abstract: An apparatus for producing particles or material-coated particles by decomposition of precursor gas in a stirred or mixed particle bed comprises a reactor vessel, an actuator assembly comprising a shaft disposed at least partially within the reactor vessel, and an actuator element coupled to the shaft and rotatable therewith. The apparatus further comprises a precursor gas supply in fluid communication with the actuator assembly. The actuator assembly is configured to circulate seed particles of a seed particle bed in the reactor vessel with the actuator element, and to introduce precursor gas from the gas supply to the seed particle bed, when seed particles are received in the reactor vessel.

    Abstract: This disclosure concerns embodiments of an annealing device and a method for annealing flowable, finely divided solids, such as annealing granular silicon to reduce a hydrogen content of the granular silicon. The annealing device comprises at least one tube through which flowable, finely divided solids are 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 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.

    Abstract: Methods of recovering hydrohalosilanes from reaction residues are disclosed. An inorganic halosilane slurry comprising (i) tetrahalosilane, trihalosilane, dihalosilane, or any combination thereof, (ii) silicon particles, and (iii) heavies is passed through a thin-film dryer to remove halosilanes and form a solid residue comprising silicon particles. Heavies also may be removed as the slurry passes through the thin-film dryer.
