Mechanism of dehydroxylation temperature decrease and high temperature phase transition of coal-bearing strata kaolinite intercalated by potassium acetate

► We have measured the thermal decomposition of kaolinite-potassium acetate intercalation complexes. ► The mechanism of dehydroxylation temperature is proposed. ► The most possible structural models of the kaolinite-potassium acetate intercalation complex have been proposed.
