Abstract
Method for manufacturing pure silver chromate in which a soluble chromate is made to react with a silver salt in a bichromate medium. The bichromate medium stabilizes the pH and makes it possible to operate in a concentrated medium. The pure product obtained may be used more particularly as a positive active substance in an electrochemical generator having a non-aqueous electrolyte, for it enables avoidance of losses in capacity during idle and storage periods of the generator.
