Abstract
A plate of copper is coated with cuprous oxide for use as a rectifier by heating the plate to a temperature at which black copper oxide is decomposed, that is above 1030 DEG C., plunging it in a protective medium liquid at that temperature and allowing it to cool whilst surrounded by such medium. The protective medium may be an alkaline earth metal fluoride, or preferably an equimolecular mixture of barium fluoride and barium chloride which melts at 1020 DEG C., and it may be located in the oven in which the plate is heated.
