Calcium chloride-based systems for metal electrodeposition

Novel eutectic mixtures have been produced using calcium chloride hexahydrate as the hydrogen bond acceptor, together with ethylene glycol donor. The liquids are found to increased conductivity, decreased viscosity and a lower glass transition temperature compared most deep solvents quaternary ammonium salts. Additionally, metal speciation was be almost same in commonly-used choline chloride: DES, despite difference water content. Calcium is an interesting component it waste product from Solvay process hence inexpensive, also has low toxicity. electrochemical properties of four different metals these were investigated, critically, shown that metallic iron, cobalt nickel could electrodeposited at ambient temperatures without need for additives.
