Abstract

Method comprises H2 redn. of a cyanide complex of the metal/s. The cyanide complex may be mono- or polymetallic pref. obtd. by the action of an aqs soln. of HCN on a hydrate of the metals, the cyanide crystals being first dried at 200 degrees C under pure dry h2 and then reduced by pure dry h2 at 700-1300 degrees C. Used for prodn. of Be, Mg, Al, Y, Lanthanides, Ti, Zn, Hf, Cr, Ga, In, & Th; alloys contg. >=2 of these; and binary or greater alloys of these metals with any other metal.
