Everyone is familiar with the word limestone; the chemical name of limestone is calcium carbonate. CaCO₃ is one of the most abundant compounds found naturally. It is present in excess in nature like eggshells, snail shells, seashells, and even pearls; calcium carbonate is present. It is present in the earth’s crust as chalk, limestone, marble, etc. Calcium carbonate has many forms which are chemically different from each other; but physically are the same like, calcite and aragonite. It is widely available and an inorganic compound with the chemical formula CaCO₃.

Calcium carbonate is present in nature; as minerals calcite, aragonite, vaterite and dolomite. Under normal circumstances, the thermodynamically stable form is hexagonal β-CaCO₃ (calcite). Other forms, like aragonite, can be prepared by precipitation at a temperature more than 85 °C, while vaterite at 60 °C. These minerals are essential at the industrial level.

Calcium carbonate is insoluble in water and an odorless fine white powder. It is a non-toxic compound and remains stable at low temperatures. When reacted with dilute acids, it releases carbon dioxide. Even if it is safe for ingestion, but excess of anything can cause damage. Similarly, excess use of calcium carbonate may lead to a milk-alkali syndrome which may cause vomiting and abdominal pain.

Calcium carbonate has a wide range of uses on an industrial and household level. The primary use of CaCO₃ is used as chalk in classrooms all over the globe. Medical supplements also use calcium carbonate. CaCO₃ also has application in paints with is also known as whitewashing. It has wide application in ceramics, iron purification, adhesive, paper making, pH adjusters in crops, etc.

We can provide 99% pure calcium carbonate for the best industrial experience.
