Owing to their swift controllable particle size and shape during synthesis, calcium carbonate is the most important material for use as a filler in the production of paper, rubber, plastic, pharmaceuticals, food, paint, textiles and many other materials pigments.
Consequently, there has been significant research to deliver easy ways of synthesising nano and microsized calcium carbonate particles at specific sizes, polymorphs and morphologies. A majority of their synthesis approaches are based on either the biomimetic or the CO2 bubbling methods.
Calcium carbonate is a chemical compound with the formula Ca CO 3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs.

Calcium carbonate has been utilized by plants and animal for the formation of their skeletons and shells. It also facilitates the calcium carbonate crystal growth on a chitosan substrate. Biochem/physiol Actions Calcium carbonate is a naturally occurring compound that reduces T4 absorption and enhancess serum thyrotropin levels.
Precipitation of calcium carbonate (lime) is a common clogging problem in microirrigation systems. Water with a pH of or higher and a bicarbonate level of at least 2 meq/l (120 ppm) is susceptible to calcium carbonate precipitation if comparable levels of calcium are present naturally in the system or if a compound that contains calcium is injected into the system.
