RESEARCH ON THE PRODUCTION OF ULTRA-PURE MOLYBDENUM
Abstract
The objective was to design and construct an apparatus capable of producing extremely pure Mo in limited quantities and to produce one pound of such metal. A single, carefully-controlled sublimation of MoCl5 yielded a highly purified product without prior purification or recourse to repeated sublimation. Hydrogen reduction of MoCl5 to metal was attempted at atmospheric pressure; to obtain substantial yields it was necessary to operate reductions at reduced pressure. Tubular deposits of metal were consolidated into bulk form by electron beam melting under high vacuum yielding a very low impurity level of gases. Problems involved in monitoring the purity of these materials and the analytical results are also presented. (Author)
