La présente invention se rapporte à un procédé de préparation d'une composition de microsphérules d'un composé oxygéné de zinc, comprenant les étapes de fourniture d'un précipité d'un composé oxygéné de zinc, d'ajustement de la conductivité dudit précipité obtenu jusqu'à obtention d'une conductivité mesurée selon la méthode de mesure de la conductivité inférieure à 3000 µS/cm, d'obtention de ladite composition de microsphérules d'un composé oxygéné de zinc à partir dudit précipité. La présente invention se rapport aussi à une composition de microsphérules d'un composé oxygéné de zinc présentant une conductivité mesurée selon la méthode de mesure de la conductivité inférieure à 3000 µS/cm ainsi que son utilisation. The present invention relates to a method for preparing a composition of microspherules of an oxygenated zinc compound, comprising the steps of providing a precipitate of an oxygenated zinc compound, adjusting the conductivity of the precipitate obtained until a conductivity measured using the conductivity measurement method of less than 3000 μS/cm is obtained, and obtaining the composition of microspherules of an oxygenated zinc compound from the precipitate. The present invention also relates to a composition of microspherules of an oxygenated zinc compound having a conductivity measured using the conductivity measurement method of less than 3000 μS/cm, and the use thereof.
