| 摘 要： | Amorphous kaolinite derivatives were prepared through mixing kaolinite with HCOOK and KOH solution. Ki-netics of kaolinite being turned into amorphous derivatvies was investigated by XRD. It showed that the transfor-mation included dynamic and diffuse controlling stages. And the active energy E1=26.8kJ·mol-1; E2=12.2 kJ·mol-1. TEM and SEM images showed that particle size of the amorphous derivatives was about 50nm. And the amorphous derivatives seemed like alumnsilicate gel， accompanied by some aggregates.
