INFLUENCE OF Zr-Fe GETTER FILTER ON Cd AND Zn DEEP REFINING OF INTERSTITIAL IMPURITIES

The paper presents the analytical and experimental studies of the process of cadmium and zinc refinement of interstitial impurities in a vacuum using a getter filter of Zr-Fe alloy. The thermodynamic analysis of reduction reactions of cadmium, zinc, carbon oxides, and zinc nitride with getter material of Zr-Fe alloy, depending on the temperature and vacuum conditions of the metals refining process have been accomplished. The experiments showed the effectiveness to use the Zr (51)-Fe (49) wt. % alloy getter filter for Cd and Zn refinement of interstitial impurities.
