Obtaining of High-Purity Titanium, Zirconium, and Hafnium by the Method of Iodide Refining in Industrial Conditions

摘要

The processes of obtaining high-purity titanium, zirconium, and hafnium by the method of thermal dissociation of iodides are discussed. The data on cleaning of the metals from impurities in glass and metal closed-type vessels are presented. The types of vessels used in industry and the conditions of raw stock pretreatment and iodide refining of titanium, zirconium, and hafnium are described.
