Thermal Decomposition of Magnesium Carbonate

MgCO3 → MgO + CO2

Genel Bakış

Magnesium carbonate decomposes when heated above 350 C to form magnesium oxide and carbon dioxide. This reaction occurs at a lower temperature than calcium carbonate decomposition because magnesium carbonate is less thermally stable. It is used in the production of magnesia for refractory applications.
