微波制备高岭石层间复合物的热解变化研究

Abstract

Abstract: The reaction activity of kaolinite and the effects of heating temperature on the performance of intercalated kaolinite complexes were investigated. The samples were characterized by TG，DTG，DTA，FT-IR，and XRD.Results showed that the reaction degrees of hydrazine and potassium acetate with kaolinite were about 96% and 89% respectively，when the particle size was small and the concentration was high.The potassium acetate intercalated in the interlayer of kaolinite was stable up to 296 ℃ and melted in the range of 296~440 ℃ and decomposed above 440 ℃.Dehydroxylation occurred on potassium acetate-kaolinite intercalated complex at 500 ℃，a lower of 150 ℃ than for the pure kaolinite.The structure of potassium acetate-kaolinite intercalation complex was stable below 330 ℃.
