Thermal decomposition of calcium carbonate - ScienceDirect

The process of thermal decomposition of calcium carbonate has been treated as one governed by simultaneous heat and mass transfer, under quasi steady state conditions, to the decomposition interface. It is believed that the surface chemical reaction is very fast and as such does not interfere in the determination of the overall decomposition rate.

Calcium carbonate needs a higher temperature to make it decompose than copper carbonate does – you must supply more heat. Today, you will be studying the thermal decomposition of calcium carbonate.

Calcium carbonate - Wikipedia

Calcium carbonate is a chemical compound with the formula Ca CO 3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs.
