Dolomite (rock) - Wikipedia. Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 65 million years in age).
Jan 19, 2015· Magnesia or magnesium oxide (MgO) is a white hygroscopic solid mineral that occurs naturally as periclase. It forms magnesium hydroxide in the presence of water [MgO + H 2 O = Mg (OH)2], but this reaction can be reversed by heating magnesium hydroxide to separate moisture. Magnesium (Mg) is the eighth most abundant element and constitutes about ...

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 when combined ...
Baltrusaitis and his group are proposing to form struvite by using magnesium oxide (MgO), dolomite (MgCO3*CaCO3) or magnesium carbonate (magnesite, or MgCO3) instead of magnesium obtained from seawater or magnesium chloride containing salt brines. MgO and MgCO3 are naturally occurring abundant minerals.
