A study on the fixation character of various cations adsorbed on kaolin minerals due to drying have been carried out. Kibushi clay, Gaerome clay, both are widely used in ceramic industry in Japan, and Zettlitz kaolin were selected as samples.The obtained results are summerized as follows:(1) The fresh raw undried Kibushi and Gaerome clays, fixed the exchangeable cations (Na+, K+, Ca++, Mg++) increasingly with drying temperature up to 50-500°C.(2) Various monoionic clays prepared by leaching with chloride solutions fixed the cations increasingly with drying temperature up to 200-300°C. The order of the fixation tendency was Li+>Na+>K+.(3) Polyvalent cations (Th++++, Ca++) adsorbed on Zettlitz kaolin were found to be fixed intensively on drying at the temperature up to 300-500°C.
