In one embodiment, the present disclosure relates generally to a method for thermally decomposing a complex precursor salt. In one embodiment, the method includes heating a salt in a reactor until a molten salt is formed, adding the complex precursor salt to the molten salt in the reactor and removing a volatile precursor halide formed from thermal decomposition of the complex precursor salt from the reactor.

High temperature decomposition of complex precursor salts in a molten salt

The present invention relates generally to production of a fluoride gas and equivalents thereof, and fluorine-doped sodium silicate glass, glass ceramics, vitro ceramics and equivalents thereof. In one embodiment, the method includes providing a salt and an oxide in a reactor, heating the reactor to produce a vapor and the vitro ceramic and removing the vapor.

Method and system for producing fluoride gas and fluorine-doped glass or ceramics

In one embodiment, the present invention relates generally to a multi-stage system for performing melt coalescence and separation, the multi-stage system. In one embodiment, the multi-stage system includes a first container for mixing a powder with a salt, the first container having an opening, a heating means coupled to the first container for heating the first container and a second container coupled to the first container.

Multi-stage system for reaction and melt coalescence and separation

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.

Methods for producing consolidated materials

A method for separating a hydrogen-rich product stream from a feed stream comprising hydrogen and at least one carbon-containing gas, comprising feeding the feed stream, at an inlet pressure greater than atmospheric pressure and a temperature greater than 200&#xb0; C., to a hydrogen separation membrane system comprising a membrane that is selectively permeable to hydrogen, and producing a hydrogen-rich permeate product stream on the permeate side of the membrane and a carbon dioxide-rich product raffinate stream on the raffinate side of the membrane. A method for separating a hydrogen-rich product stream from a feed stream comprising hydrogen and at least one carbon-containing gas, comprising feeding the feed stream, at an inlet pressure greater than atmospheric pressure and a temperature greater than 200&#xb0; C., to an integrated water gas shift/hydrogen separation membrane system wherein the hydrogen separation membrane system comprises a membrane that is selectively permeable to hydrogen, and producing a hydrogen-rich permeate product stream on the permeate side of the membrane and a carbon dioxide-rich product raffinate stream on the raffinate side of the membrane. A method for pretreating a membrane, comprising: heating the membrane to a desired operating temperature and desired feed pressure in a flow of inert gas for a sufficient time to cause the membrane to mechanically deform; decreasing the feed pressure to approximately ambient pressure; and optionally, flowing an oxidizing agent across the membrane before, during, or after deformation of the membrane. A method of supporting a hydrogen separation membrane system comprising selecting a hydrogen separation membrane system comprising one or more catalyst outer layers deposited on a hydrogen transport membrane layer and sealing the hydrogen separation membrane system to a porous support.
