Abstract
A process and apparatus for producing metal foil comprises supplying an isotopically polished continuous cathode, a high volume turbulent flow of electrolyte and rigorous filtration to exclude chlorides, sulfides, organics and other impurities from the electrolyte. The foil so produced is free from micro-voids and able to withstand substantially higher biaxial stresses than conventional electrodeposited foil. The micro void free structure also decreases the diffusion rate of an underlying substrate.
