However the kinetic parameters estimated by the quasi isothermal method turned out in lower values indicating the need to control the reactor atmosphere.

The decomposition of limestone during the firing process is mainly based on the decarbonation of CaCO3. In the case of crystalline limestone it is the decomposition of calcite crystals. In this study different limestone properties on the course of decarbonation are studied. Therefore the samples are determined from a geological and physicochemical point of view geological age
