  • Bimolecular coated calcium carbonate and process of production thereof
    Patent number: 6342100
    Abstract: Bimolecular coated calcium carbonate and a process for controlled surface treatment of calcium carbonate according to which an amount of coating determined from the mean particle diameter (dp) of the calcium carbonate is contacted with the calcium carbonate particles. The way in which the amount of coating agent is determined enables purposeful control of the properties of the coated calcium carbonate particles to adapt them for use as functional filling materials in different technical applications.
