    Highlights

    We produce precipitated calcium carbonate (PCC) in various crystal modifications: calcite, aragonite and vaterite. In addition, the particle shape can be varied in a very large number of ways. The physical parameters for each of these crystal structures, e.g.

    • particle size and grain size distribution.
    • single particles or agglomerates of primary crystals
    • specific surface area, pore volume, absorption capacity (oil absorption value).

    can be modified to suit the application.

    This allows light scattering properties, opacity, rheology and many other application-related properties to be optimized.

    Wherever

    • a high degree of chemical purity,
    • a high level of whiteness and opacity,
    • exactly defined crystal structures,
    • exceptional fineness and close particle size distribution

    are called for, our PCC is the right choice. Its versatility is evident in its wide variety of applications.
