Analysis, fungicide, catalyst, oxidation
inhibitor for metals.
Copper(II) phosphate is used as organic catalyst, fertilizer, emulsifier, corrosion inhibitor for phosphoric acid, metal protectant, and animal feed additive.
Copper(II) phosphate trihydrate, Cu3(PO4)2·3H2O, [7798-23-4], MW 434.61, is a pale-blue powder that is insoluble in cold water and slightly soluble in hot water, but it dissolves in ammonia solution and mineral acids. It is prepared by the reaction of copper(II) sulfate solution with soluble alkali phosphates and it precipitates as a voluminous, almost gelatinous material. Copper(II) phosphate trihydrate is used as a corrosion inhibitor and fungicide.
