In one embodiment, the present invention relates generally to a method for reutilizing ionic halides in a production of an elemental material. In one embodiment, the method includes reacting a mixture of an ionic halide, at least one of: an oxide, suboxide or an oxyhalide of an element to be produced and an aqueous acid solution at moderate temperature to form a complex precursor salt and a salt, forming a precursor halide from the complex precursor salt, reducing the precursor halide into the element to be produced and the ionic halide and returning the ionic halide into the mixture of the reacting step.

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.

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.

The invention relates to a method for producing activated, substantially monodisperse, phosphorescent particles and particles formed thereby. The method suspends substantially monodisperse, phosphor-precursor particles in a fluidizing gas and then introduces a reactive gas to contact the suspended phosphor-precursor particles. Heating the suspended phosphor-precursor particles to a reaction temperature then forms unactivated phosphorescent particles. In another embodiment, the phosphor-precursor particles may be heated to a reaction temperature where they decompose to form the unactivated phosphor particles. The unactivated phosphorescent particles suspended within the fluidizing gas are activated by heating the unactivated phosphorescent particles to an activation temperature forming activated, substantially monodisperse, phosphorescent particles.
