Thermal Decomposition of Calcium Carbonate (solutions ...

Calcium carbonate is heated strongly until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.

Thermal decomposition of calcium carbonate at various gas temperatures and compositions, and in samples of different diameters. The only significant variation was found to be that between the diffusion coefficient and the gas temperature. The actual nature of the relationship could not be ascertained from the results and so a linear correlation was used. The diffusion coefficient results are ...
