Calcium carbonate is a white, odorless, and tasteless chemical compound with the formula CaCO3, widely recognized for its versatile applications in various industries. It is a key component of natural substances like limestone, chalk, and marble. In the industrial realm, calcium carbonate is used as a filler in the production of plastics, paints, and coatings, where it enhances product strength and opacity. It is also an essential ingredient in the paper and pulp industry for improving paper whiteness and smoothness. In agriculture, calcium carbonate is employed to amend soil pH and provide calcium to plants. Furthermore, it is a common dietary supplement for calcium enrichment and antacid medications to alleviate heartburn and indigestion. The diverse utility of calcium carbonate highlights its significance in both industrial and consumer sectors.
