Abstract
Abstract 1. An electrolyte for a fused electrolyte cell consisting essentially of a mixture of 45 to 55 mole percent of CaCl 2 ; 30 to 54 mole percent of NaCl; and 1 to 15 mole percent of KCl, containing proportions of each component substantially as determined by a three system diagram of such components; and a depolarizing agent.
