Abstract
A method for the inhibition of corrosion in particulate zinc, comprises the step of subjecting the zinc in the form of an alkaline slurry to the action of a corrosion inhibiting effective amount of a corrosion inhibitor which is at least one oxide selected from the oxides of antimony, bismuth, cadmium, gallium, indium, lead, mercury, thallium and tin, and which preferably constitutes 0.05-4.0 parts by weight, based on the weight of the zinc. The particulate zinc may be that recovered electrolytically from at least partially spent electrolyte from a zinc-air battery. Corrosion inhibited particulate zinc which has been treated according to the above method, as well as a mixture of (untreated) particulate zinc with such treated zinc, also form part of the invention.
