Calcite, with the CAS number 13397-26-7, is a naturally occurring mineral composed primarily of calcium carbonate (CaCO3). It is characterized by its rhombohedral crystal structure and can appear in various colors, including white, colorless, yellow, and even shades of blue or green, depending on impurities. Calcite is known for its excellent cleavage, which allows it to break along specific planes, resulting in smooth surfaces. It exhibits a vitreous to pearly luster and has a hardness of 3 on the Mohs scale, making it relatively soft compared to other minerals. Calcite is soluble in dilute acids, releasing carbon dioxide gas, a property that is often utilized in geological and environmental studies. It plays a significant role in the carbon cycle and is a major component of sedimentary rocks like limestone and marble. Additionally, calcite is widely used in various industries, including construction, agriculture, and as a pH regulator in water treatment processes. Its optical properties, such as birefringence, make it valuable in optical applications as well.
