METHOD FOR PRODUCING HYDRATED ZINC HYDROGEN PHOSPHATE

摘要

The present invention relates to a method for producing hydrated zinc hydrogen phosphate (Zn₃(HPO₄)₃, 3H₂O) from zinc oxide ZnO and phosphoric acid H₃PO₄, mainly characterized in that it comprises the following steps: placing the phosphoric acid in a reactor, dissolving a determined quantity of zinc oxide in the phosphoric acid to form a reaction mixture, said determined quantity of zinc oxide being chosen so as to have a weight ratio between the phosphoric acid and the zinc oxide H₃PO₄/ZnO greater than or equal to 1, mechanically mixing the reaction mixture to form the hydrated zinc hydrogen phosphate.
