WebDec 2, 2011 · Subsequently, the thermal decomposition process of basic magnesium carbonate in air was studied by thermogravimetry-differential thermogravimetry (TG-DTG). The results of XRD confirm that the chemical composition of basic magnesium carbonate is 4MgCO 3 ·Mg (OH) 2 ·4H 2 O. Decomposition [ edit] At high temperatures MgCO 3 decomposes to magnesium oxide and carbon dioxide. This process is important in the production of magnesium oxide. [6] This process is called calcining : MgCO3 → MgO + CO2 (ΔH = +118 kJ/mol) The decomposition temperature is given as 350 °C (662 °F). See more Magnesium carbonate, MgCO3 (archaic name magnesia alba), is an inorganic salt that is a colourless or white solid. Several hydrated and basic forms of magnesium carbonate also exist as minerals. See more Magnesium carbonate is ordinarily obtained by mining the mineral magnesite. Seventy percent of the world's supply is mined and prepared in China. Magnesium carbonate can be prepared in laboratory by reaction between any soluble magnesium … See more The primary use of magnesium carbonate is the production of magnesium oxide by calcining.
