The first application of vacuum techniques to the metallurgical industry was made in the early part of this century by Rohn, a German, who developed vacuum technology to a production status in the specialty metals business. Although extensive use of vacuum processing technology was made in the lamp and electrical industries, the methods used were considered to be impractical up to about ten years ago even though remarkable improvements were made during World War II. Wartime demands for magnesium and for uranium which necessitated the use of a high vacuum in their production led to the perfection of mechanical pumps, diffusion pumps and vacuum gauges suitable for use in large-scale operations.
