For calcite and aragonite production, 221 g of CaCl 2 and 276 g of K 2 CO 3 were solubilized in two separate two-liter beakers of deionized water. To synthesize calcite, the calcium solution was slowly added to the potassium solution, and it was aged and mixed well for 16 h at 600 RPM. ... three anhydrous calcium carbonate polymorphs, calcite ...
Found all over the world, calcite is the most stable form of calcium carbonate and is the main mineral found in limestone. We find calcite in the ocean, in shells or hard parts of marine organisms like plankton, coral reefs, types of red algae, oysters and sponges. There is even a stalactitic form of calcite found in limestone caves.

Microbially induced calcite precipitation (MICP) refers to the formation of calcium carbonate from a supersaturated solution due to the presence of their microbial cells and biochemical activities (Bosak 2011).During MICP, organisms are able to secrete one or more metabolic products (CO 3 2−) that react with ions (Ca 2+) in the environment resulting in the …
Almost every product in our daily lives either contains calcium carbonate or has some association with the mineral during its production. The Earth's crust contains more than 4% calcium carbonate. As a result, the three calcium carbonate minerals – calcite, aragonite and vaterite – are among the most important rock-forming minerals.
Also used as a filler in coating pigments and paints, calcium carbonate is valued for its unique white color. In some cases, up to 30 percent of the weight of certain paints is …
Calcium carbonate is an essential and versatile mineral which finds its way into our daily life. ...
