Essay

The dissertation is devoted to researches of the basic principles of processes of obtaining and refining of nuclear-purity hafnium and also study of its physical properties.Basic stages of obtaining of hafnium tetra fluoride (HTF), purification its by vacuum sublimation method, obtaining of double metal alloys Hf-Me by method of recovery of HTF by calcium and fining meltings of these alloys with purpose of obtaining ingots of pure hafnium were investigated and tested in laboratory, and plant conditions in this thesis at the first time. The complex of researches of physic-mechanical and corrosion behavior and also reactor tests was conducted, and a number of features, typical for this metal are detected.
