Abstract:
The kinetics of the thermal decomposition of calcite and CaCO 3 ‐„samples”︁ of defined preparation were investigated. It was found, that the rate of decomposition of calcite is determined by the formation of crystal nuclei and by the growth of the CaO‐phase, both of which are dependent on pressure. In the decomposition of the samples, however, the dependence on pressure of the formation of CaO crystal nuclei is negligibly small. Hence the dependence on pressure of the growth reaction can be obtained directly from the decomposition curves, the growth reaction is found to be a linear function of the reciprocal CO 2 ‐pressure. The conditions are determined for which the reaction is proportional to the phase interface and hence is of the order 2/3. From the reaction mechanism derived a formula is obtained — in agreement with experimental data — for the rate of growth of the solid phase formed by the reaction magnified image
