Calcium Carbonate is an exceptional mineral. The chemical formula CaCO3 covers a raw material, which is widespread throughout nature, whether dissolved in rivers and oceans, in molten form as "cold" carbonatite-lava, or solid as mineral in the form of stalactites, stalagmites or as the major constituent of whole mountain ranges. Plants and animals need calcium carbonate to form their skeletons and shells. It's a common substance found in three different forms like Chalk , Limestone and Marble .
Calcium carbonate is by far the most important mineral for compounding with polymers. By weight it accounts for more than 60% of the filler and reinforcements market. Main applications include plasticised and rigid PVC, unsaturated polyesters, polypropylene and polyethylene. Other important areas of use include rubber, foamed latex carpet-backings, sealants and adhesives.Calcium carbonate is not only a filler added to reduce costs and extend petroleum based resources, many properties of the plastic can be influenced by the use of calcium carbonate. Breathable PE-films for hygiene products and the building industry, for example, can only be produced with the incorporation of a filler such as calcium carbonate.
In paints and coatings, calcium carbonate has established itself as the main extender. Fineness and particle-size distribution can contribute to the opacity of coatings. Moreover, calcium carbonate can offer improvements in weather resistance, anti-corrosion and rheological properties, coupled with low abrasiveness, low electrolyte content, and a pH stabilizing effect. In water-based systems calcium carbonate reduces the drying time.
Over the last 30 years, the use of calcium carbonate has grown significantly as technology in the paper industry has moved from acid to neutral sizing. Today, calcium carbonate is the most widely used mineral in paper-making. GCC and PCC are used both as a filler and a coating pigment, and help produce papers with high whiteness and gloss and good printing properties.
As a natural product, calcium carbonate is perfect for environmental protection applications. For example, flue gas desulphurization, drinking water treatment, waste water treatment and forest and lake liming for the neutralization of acid rain, are all growth areas for the use of calcium carbonate. It has a natural buffer-effect and works as a pollution-filter.
Calcium fertilizers were one of the first to be widely used. The Greeks and Romans were aware of their attributes. Their use guarantees an adequate supply of calcium to plants and stabilizes the pH-value of the soil. These characteristics make calcium carbonate an important fertilizer for the agriculture and forestry sectors. Other Agricultural-related uses of calcium carbonate include its use as a calcium supplement in animal feed compounds.
Calcium carbonate has found an innovative application in the concrete market. It is increasingly used as a quality filler in concrete applications, such as concrete wares (paving-stones,tubes, sewage-tanks), ready-mixed concrete and prefabricated elements. It improves the concrete density, pre-stability and durability. Its stable colour quality increases the aesthetics which make it very suitable for architectural applications.
Glass, ceramics and blackboard chalk, together with cleaning, dental care and cosmetic products are produced by the wide range of industrial manufacturers who rely on calcium carbonate.
