Abstract : The basic principles of the zone refining process are discussed. An electron beam zone refiner was built and has been used to successfully produce zone refined molybdenum rods. Additionally, a commercially manufactured induction zone refiner was purchased and several 1/4 in. diameter zone refined molybdenum rods have been purified with it. Improvements in the filament design have compensated for some of the problems created by molybdenum vapor deposition. (Author)
