Abstract：The effect of hydrazine concentration on the intercalation rate is investigated as the Maom-ing kaolinite is intercalated by hydrazine. It has been found that there exist a low threshold and opti-mized value of hydrazine concentration for the kaolinite intercalation. In addition to the common space1.04 nm, a new interlayer space distance 0.97 nm, was observed when the kaolinite was intercalatedby high concentration hydrazine (≥24 mol/L). The appearance of such new space is attributed tokeying of the -NH2 moiety of hydrazine into the siloxane ditrigonal cavity, according to infrared spec-troscopy.
