Abstract
Calcite thermally dissociated in the presence of various kaolinites was partially preserved as a discrete phase. Proximity of the clay caused corrosion of the calcite rhombs, even before decarbonation occurred and CaO formed. The kaolinite sample used determined the CaCO3 polymorph formed on recarbonation and polymorphs with very different morphologies were obtained. Volatiles evolved on heating kaolinite also affected the recarbonation reaction, but to a lesser extent than contact with the clay.
