A PROCESS based on mechanical ball milling promises to produce alkali metal hydrides (AMHs) at lower cost than current methods, believe its developers at the U.S. Dept. of Energy's Ames Laboratory, Ames, Iowa. The process rapidly converts ductile alkali metals into AMHs without the use of solvents and catalysts, they add. Moreover, the reactive mechanical milling avoids the hazards posed by the high temperatures used in conventional production.
