DOLOMITE (Calcium Magnesium Carbonate)
Dolomite is also slightly harder, denser and never forms scalenohedrons (calcite's most typical habit). Dolomite differs from calcite, CaCO3, in the addition of magnesium ions to make the formula, CaMg(CO3)2. The magnesium ions are not the same size as calcium and the two ions seem incompatible in the same layer.

Dolomite – Virtual Museum of Molecules and Minerals
Dolomite. Dolomite is a calcium/magnesium carbonate mineral. It has a formula unit composition of CaMg (CO 3) 2. Dolomite has a trigonal crystal system with rhombohedral habit. In ideal dolomite, calcium and magnesium are separated into completed separate planes, quite unlike magnesian calcites in which Mg randomly substitutes for Ca.
What Is the Chemical Formula for Limestone? - Reference
The chemical formula for calcium-magnesium carbonate is CaMg(CO3)2. Calcium carbonate is commonly known as calcite,and calcium-magnesium carbonate is commonly known as dolomite. In nature, limestone deposits are very rarely composed of pure calcite or pure dolomite, although such deposits have been found.

Notes. Dolomite as a ceramic material is a uniform calcium magnesium carbonate. In ceramic glazes it is used as a source of magnesia and calcia. Other than talc, dolomite is the principle source of MgO in high temperature raw glazes. 'Dolomite matte' stoneware glazes, for example, are highly prized for their pleasant 'silky' surface texture. Dolomite by itself is refractory, but …
