摘要
The present invention relates to a process for the manufacture of hydrated zinc hydrogen phosphate (Zn3 (HPO4) 3, 3H2O) from zinc oxide ZnO and phosphoric acid H3PO4, mainly characterized in that it comprises the steps following: - 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 mass ratio between phosphoric acid and zinc oxide H3PO4 / ZnO greater than or equal to 1, - mechanically kneading the reaction mixture to form hydrated zinc hydrogen phosphate.
