OSTI ID:4118335
A method for purifying beryllium from halogen impurities, especially chlorine, is outlined in which beryllium is milled to a powder of particle size <100 mu and heated to 825 to 875 deg C at reduced pressures (0.1 to 1 mu Hg) for 2 to 12 hr, or long enough to volatilize the impurities. An example of this method is given in which the chlorine impurity in electrolytically produced beryllium is reduced from 0.1 to 0.007 wt.%. (D.L.C.)
