摘要：
Amorphous kaolinite derivatives were prepared through mixing kaolinite with HCOOK and KOH solution. Kinetics of kaolinite being turned into amorphous derivatvies was investigated by XRD. It showed that the transformation 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.
