ABSTRACT:
An aqueous sodium carbonate solution is added in an equivalent amount to an aqueous silver nitrate solution (Ag=100 g/L) under stirring and, with nitric acid and sodium hydroxide being added to adjust the pH to 5.5-6.5, a silver carbonate precipitate is formed and subsequently washed thoroughly and dried at 250.degree. C. or below to produce a silver oxide powder, which satisfactory characteristics for use in cells, as exemplified by high water absorption, good shape of granules, high strength, non-stickiness to the molding punch, high fluidity and low residual carbon content. The pellet of the powder has high cell capacity.
