· Dolomite (CaMg(CO 3) 2) is a very cheap water insoluble sedimentary carbonate rock which consists of the Ca 2+ and Mg 2+ ions with double-layered carbonates [17], [18], [19]. Although dolomite has various structural characteristics, it is best known for its saddle-shaped crystals that help to its high stability at ∼350 °C [18].
