Calcite - an overview ScienceDirect Topics

Calcite is a carbonate mineral CaCO 3 (Fig. 1.13), and the most stable polymorph of calcium carbonate (calcite, aragonite, and vaterite).The color is milky white due to transparency with a yellow tint. The luster is vitreous with a white streak. The specific gravity of the mineral is 2.71 g/cm 3.The calcite in purest form contains 56.03% CaO and 43.97% CO 2.

2021-6-1  Calcite characteristics: Calcite is a calcium carbonate mineral with a wide distribution. There are many kinds of crystal shapes, and many square pieces can be obtained by hitting calcite, hence the name calcite. This type of mineral has very high hardness and stable chemical properties, so it has a very high application value.

Mystery solved: Why seashells’ mineral forms differently ...

2015-3-2  For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth’s oceans: Why does calcium carbonate, the tough material of seashells and corals, sometimes take the form of calcite, and at other times form a chemically identical form of the mineral, called aragonite, that is more soluble — and therefore more vulnerable to ocean acidification?
