What Does Calcite Mean?

Calcite is a mineral belonging to the carbonate group of materials that is abundant on earth. More specifically, it is a form of calcium carbonate with the chemical formula CaCO3. Calcite can be found in a wide variety of shapes, sizes and colors.

Calcite can be used for a variety of purposes, especially in the construction industry. Calcite is frequently used in the form of polished limestone and marble to add aesthetic appeal to both residential and commercial structures. Calcite is also a major ingredient in cement mixes. As a result of this, calcite is found in roads, floors, pillars, bridges and many other instances where concrete structures are used. Calcite is also used as a scale inhibitor and to neutralize acids with the intent of reducing the likelihood of corrosion.


Corrosionpedia Explains Calcite

Calcite is very plentiful and makes up a sizable portion of the earth’s crust. Calcite deposits are frequently present in cave formations. Calcite can be extracted from limestone, which is largely made up of calcite. Calcite also is found in marble, which is a form of limestone.

Calcite is the most regularly occurring type of calcium carbonate. Aragonite, another mineral form of calcium carbonate, is polymorphous to calcite, which means that although they have the same chemical composition (that of calcium carbonate) they have a different crystal structure. Even though there is a difference in crystal structure, calcite and aragonite have similar uses.

Blackboard chalk has a significant amount of calcite in it.
