Is limestone calcite? Calcium carbonate rock with (minerals) as the main component.
Mainly formed in shallow sea environment, it can be directly processed into stone and burned into quicklime.
Calcium carbonate is a compound with the chemical formula of CaCO3 and the number of CAS is 47 1-34- 1. It is a common substance on earth and can be found in rocks. It is the main component of animal shells and snail shells.
It exists in nature as two minerals, calcite and aragonite. Calcite belongs to hexagonal system. Pure calcite is colorless and transparent, generally white, containing 56%CaO and 44%CO2, with a density of 2.7 15g/cm3 and a Mohs hardness of 3, showing brittleness.
Aragonite belongs to orthorhombic system, rhombic crystal, gray or white, with density of 2.94g/cm3 and Mohs hardness of 3.5-4, with dense properties.
