Abstract
Metal-ammonia solutions (1.5 to S mole per cent alkali metal) with added traces of water and oxygen can be transferred into a high-conducting state by a dc current forced through the solution with a critical voltage and critical power dissipation, respectively. This high-conducting state is stabilized by the viscous gel formed by the reaction of the metal with the added impurities.
