摘要： Disclosed in the invention is a method for separating zirconium oxide/hafnium oxide by pyrometallurgy. The mixture of zirconium oxide/hafnium oxide, carbon and pure bromine react one hour at 650°C to get the zirconium and hafnium bromide, then the zirconium and hafnium bromide are added to molten salt mixture for distillation separation, and the rectifying tower bottom is maintained two hours below 357°C, to get the non-target substance; and maintained five hours at 357°C to collect the target substance zirconium tetrabromide; the residue in the reactor is retained, then rectification separation is performed in the same device, heated to 400°C to retain more than five hours, to get hafnium tetrabromide, then the zirconium tetrabromide and hafnium tetrabromide are replaced by magnesium to get the pure zirconium and pure hafnium. Since the separation effect is good and equipment investment is economical, it is easy to achieve industrialization. This invention technology can fill the gap in china, to make great contributions to the localization of zirconium and hafnium nuclear materials.

摘要： A process for treating a zirconium containing feedstock includes fluorinating a feedstock comprising dissociated zircon ('DZ') to obtain a zirconium fluorine compound and a silicon fluorine compound. The zirconium fluorine compound is separated from the silicon fluorine compound. Optionally, the zirconium fluorine compound is reacted with a non-fluorine halogen, an alkali metal non-fluorine halide or an alkaline-earth metal non-fluorine halide, thereby to obtain a zirconium non- fluorine halide. The zirconium fluorine compound or, when present, the zirconium non-fluorine halide is subjected to plasma reduction, in a plasma reduction stage, in the presence of a reductant, to obtain metallic zirconium.

摘要： The present invention relates to high-purity zirconium or hafnium with minimal impurities, particularly where the content of alkali metal elements such as Na, K; radioactive elements such as U, Th; transitional metals or heavy metals or high melting point metal elements such as Fe, Ni, Co, Cr, Cu, Mo, Ta, V; and gas components such as C, O, etc. is extremely reduced, as well as to an inexpensive manufacturing method of such high-purity zirconium or hafnium, thereby reducing the impurities hindering the guarantee of the operational performance of semiconductors. The present invention further relates to an inexpensive and safe manufacturing method of high-purity zirconium or hafnium powder from hydrogenated high-purity zirconium or hafnium powder.
