RESEARCH ON THE PROBLEM OF DUCTILITY IN BERYLLIUM

Abstract

The rate of corrosion of silver by dry chlorine at 600C and one atmosphere pressure was determined to be about one-thousandth of an inch in one hundred hours, a figure sufficiently low to make the use of silver apparatus in the halide reduction process entirely feasible. Several models of silver chloride valvesevllves were constructed and tested. Difficulties in operation rendered this type valve impractical, and it was decided to control the flow of reactant vapors by adjusting helium pressure. An experiment has been designed and equipment assembled to study the chlorination reaction of beryllium with respect to required flow rates of gases and the nature of the condensate. An induction furnace has been designed and constructed for the zone-refining of commercial grade beryllium, and construction of the electron-beam equipment for ultra-high vacuum zone-refining initiated.
