ASSAYING THE INDUSTRIAL METHODS RESTORATION OF JOINTS ZIRCONIUM TO METAL OF KERNEL PURITY

In papers it is presented a process of reception zirconium of kernel purity on an instance of the existing circuit design which is applied on one the factories of Ukraine. It consists of following stages: concentrate rolling-on, upgrading, branch of impurities, zirconium and hafnium separation, restoration and fusion. Existing industrial methods of restoration joints of zirconium to metal are analyses. Most widespread of them are a magnesium thermal, calcium thermal and electrolytic. Each of methods has the advantages and deficiencies. Calcium thermal is most simple direct method manufacture of zirconium and its alloys, he allows to gain zirconium alloys immediately in the course of restoration and at use of induction furnaces with cold crucibles for its further fusion can consider the given expedient one of the most perspective.
