Abstract

The reactions of Georgian kaolinite with saturated solutions of alkali metal Chlorides, potassium acetate and with solid salts resp. were followed by XRD, FTIR and TA-MS methods. The results show that in the case of solid MCl and solutions thereof already at room temperature alkali metal ions have been incorporated into kaolinite. The quantity of incorporated cations increased with rising temperature. CH3COOK was intercalated into the interlayer spaces. The solid state reactions and the gaseous reaction products up to 1000 °C were followed by different methods. The crystal phases formed in the course of the reactions between kaolinite and the decomposed salts have been investigated up to 1300°C. The reaction mechanisms on the basis of experimental data and literature are discussed.
