摘要： A chemical vapor deposition (CVD) reactor system has a reaction chamber enclosed by a reaction chamber wall with an inner surface disposed towards the interior of the chamber. At least a portion of the wall is a heat control layer that faces the chamber and that consists of a material, such as electrolytic ally deposited nickel, that has an emissivity coefficient, as measured at 300K, of 0.1 or less and a hardness of at least 3.5 Moh. Polycrystalline silicon is produced from silicon-rich gases using such a CVD reactor system.

摘要： Fluidized bed reactor systems for producing high purity silicon-coated particles are disclosed. A vessel has an outer wall, an insulation layer inwardly of the outer wall, at least one heater positioned inwardly of the insulation layer, a removable concentric liner inwardly of the heater, a central inlet nozzle, a plurality of fluidization nozzles, at least one cooling gas nozzle, and at least one product outlet. The system may include a removable concentric sleeve inwardly of the liner. In particular systems the central inlet nozzle is configured to produce a primary gas vertical plume centrally in the reactor chamber to minimize silicon deposition on reactor surfaces.
