STURCAL and CALOPAKE

Sturcal and Calopake belong to the family of precipitated calcium carbonates (PCC) produced by the direct carbonation of hydrated lime, known as the ‘milk of lime’ process. These precipitated calcium carbonate grades are microcrystalline, white powders characterized by their high chemical purity, controlled particle shape and narrow particle size distribution. Although a number of different calcite crystal forms are possible, these products consist of agglomerates of scalenohedral or cubic calcite crystals.
