    In the past decade, we have all witnessed the development of metals with respect to high purity or controlled impurity. Such work has progressed as the result of the cooperative efforts of the metallurgist, engineer, physicist and chemist. At the Bell Telephone Laboratories, there are innumerable research and development problems involving a wide range of materials for which the chemist must provide adequate means of testing. Vacuum fusion analysis is one such method which must progress in technique and development to meet the demand. Because of the common knowledgeof this technique which has been widely published, only the apparatus and the highlights of the procedure are outlined here. This presentation covers some aspects in the study of nickel used in the electronic field. Then, with some of these projected thoughts in mind, some current problems that have developed in extending the vacuum fusion method to a study of other metals, namely, germanium, silicon, tantalum and molybdenum are reviewed. No doubt, many laboratories have carried out extensive studies of one or more of these metals and have encountered some of the difficulties presented here.
