DOLOMITE 500#

CAS Number: 16389-88-113983-17-0
EC Number: 240-440-2
Chemical Name: Calcium Metasilicate, Dolomite, Calcium Metasilicate, Dolomite

Dolomite 500# is a double carbonate of Magnesium and Calcium (CaCO3. MgCO3) Theoretically, it contains 21.7 MgO and 30.4 % CaCO3 and the remaining being CO2. How ever in nature much variation takes place in the composition. It is sedimentary origin and is supposed to have been formed due to alteration of Calcium Carbonate sediments or rocks, by seawater rich in magnesia.
