Abstract

The invention relates to a method of manufacturing ZnS particles by wet-chemical precipitation from aqueous zinc salt solutions, ZnS being precipitated onto nuclei introduced into the solution. Nuclei of a controlled particle size and particle size distribution are obtained in that the nuclei of the aqueous precipitation solution are added in the form of a water-soluble organosol which contains the nuclei.
