Zirconium electrorefining

Electron-beam melting of zirconium has been used to remove the more volatile impurities such as iron, but the relatively high volatiUty of zirconium precludes effective purification. Electrorefining is fused-salt baths (77,78) and purification by d-c electrotransport (79) have been demonstrated but are not in commercial use. [Pg.431]

Monovalent Halides. Zirconium monochloride [14989-34-5], ZrCl, was discovered during electrorefining studies of zirconium in a SrCl2—NaCl—ZrCl4 melt intended to produce pure ductile hafnium-depleted zirconium from cmde zirconium anodes (180—181). The monochloride is also called Zirklor. It is obtained as black flakes with a graphite sHp-plane behavior and was proposed as a lubricant (182,183). [Pg.436]

Magnesium chloride and excess magnesium are removed by distillation at reduced pressure. Pure zirconium may be prepared by several methods that include iodide decomposition process, zone refining, and electron beam melting. Also, Zr metal may be electrorefined in a molten salt bath of potassium zirconium fluoride, K2ZrFe... [Pg.997]
