  • Patent number: 4894093
    Abstract: Barium sulfate which has a chemically reactive surface is produced by a precipitation of barium ions by means of sulfate ions in an aqueous medium. In order to provide barium sulfate as a filler having functional properties, the precipitation is effected as a coprecipitation in the presence of additional anions of water-soluble compounds, which anions are coprecipitable with barium ions to form difficulty soluble barium compounds. The reactive product which contains heteroatoms is subjected to an aftertreatment which is suitable for the use that is intended in a given case.
