Calcium carbonate

Calcium carbonate (CaCO₃), is a natural mineral from the carbonates group. It occurs naturally as limestone or is produced industrially as precipitated calcium carbonate (PCC). Calmit’s precipitated calcium carbonates impress with its high purity, precisely defined grain sizes and excellent physical properties. This makes them particularly suitable for demanding applications in many different industries.

Calcium carbonate is an indispensable component of modern industrial processes. In the construction industry, it is used as an aggregate for concrete, as a filler for asphalt and as a raw material for cement production. The paper industry uses precipitated calcium carbonate (PCC) to improve whiteness and opacity. In the plastics industry, PCC serves as a functional filler that enhances mechanical properties and improves surface appearance. Paints and coatings benefit from the brightness and opacity of PCC, acting as a substitute for titanium dioxide and in adhesives and sealants its rheological properties are crucial. In agriculture, calcium carbonate is used for soil improvement and pH regulation.

Thanks to its regional extraction, manufacturing and CO₂-binding properties, Calmit´s precipitated calcium carbonate is not only high-performance but also sustainable.
