بيت /thermal decomposition of calcium carbonate
* Thermal stability of group1 and group2 carbonates ... * Small and highly charged metal ions possess more polarizing power and hence facilitates the decomposition of carbonate ion into carbon dioxide and oxide ion. ... Calcium carbonate is present in the marble stone. This is decomposed to carbon dioxide when come into contact with acids.

Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates). calcium carbonate calcium oxide + carbon dioxide.

We demonstrate a novel approach for synthesizing porositycontrolled calcium carbonate by onestep thermal decomposition of various calcium carboxylate derivatives as well as their mixtures with different molar ratios. By varying the volume content of calcium in the calcium compounds or mixtures, the resulting porous calcium carbonate exhibits distinct porosity and structures that are very promising for .

Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition.
