Calcium Carbonate Usages

Coatings: 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 usages include 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.

Paper: 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.

Plastics: 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.

Environment: As a natural product, calcium carbonate is perfect for environmental protection applications. For example, flue gas desulphurization, drinking water treatment, wastewater 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. These properties, likewise, apply to the derivative products.

Agriculture: 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. Every year, in Europe alone, more than 4.5 million tons are supplied to this market. Other agricultural-related uses of calcium carbonate include its use as a calcium supplement in animal feed compounds.

Others: A wide range of industrial manufacturers who rely on calcium carbonate, produced glass, ceramics, and blackboard chalk, together with cleaning, dental care, and cosmetic products. As a natural mineral, calcium carbonate has a multitude of characteristics that make it an ideal raw material for widely differing uses.
