Abstract: Example systems are described for producing solar grade silicon from a silicon-generating reaction and recycled silicon particles. In one example, a system for manufacturing high purity solid silicon includes a reactor and a cooling chamber. The reactor includes one or more outlets and a reactor chamber. The one or more outlets are configured to receive a silicon tetrahalide, a reducing agent, and recycled silicon particles. The reactor chamber is configured to react the silicon tetrahalide and the reducing agent to produce fresh silicon, a halide salt, and reaction heat. The reactor chamber heats the recycled silicon particles, the fresh silicon, and the halide salt using at least a portion of the reaction heat to form molten silicon and molten halide salt. The molten silicon includes melted fresh silicon and melted recycled silicon particles. The cooling chamber is configured to cool the molten silicon to form the solid silicon.

Abstract: A method and apparatus for modifying the configuration of a network device, such as a router, using a two-stage configuration model is provided. A first request for a change in configuration of a network device is received. Configuration data that describes the change in configuration of the network device is stored in a buffer. A second request to modify the current operational state of the network device to reflect the configuration data stored in the buffer is received. An exclusive lock on the network device is obtained. The current operational state of the network device is modified to reflect the configuration data stored in the buffer. Multiple users may modify the network device without interfering with one another because conflicts are avoided through use of an exclusive lock. Requests of different management operations may be contained within XML documents that are transmitted from the client to the network device.

Abstract: Aspects of the invention include methods for producing purified semiconductor or metallic materials. In one embodiment, the methods include admixing a particulate composition of a material, for instance, a metal, with a metal halide to produce a metal-metal halide admixture. The admixture is then heated to a temperature that is above the material's melting point in a container that is chemically and physically stable at that temperature. The molten admixture is allowed to segregate into a lower of the material and an layer of the metal halide and cooled. The metal halide is then separated from the material and a purified semiconductor or metallic material is thereby produced. Also provided are purified material crystals, shaped ingots and/or taper, sheet, or ribbons produced by such methods, as well as the silicon chips and solar panels in which such products are employed.
