Microwave Assisted in KAc/Longyan Clay Intercalated Composites

Abstract

In this study, a series of comparative studies for the effect of potassium acetate(KAc) on the physical properties of the Longyan Clay were performed. Microwave was used to promote the intercalating process. The d-spacing increased with the increasing adding amount. As the addition of KAc reached 20wt.%, the d-spacing of illite[002] increased from 9.9505Å to 10.1311 Å, the kaolinite[001] increased from 7.1439Å to 7.2251 Å, and a new diffraction peak emerge at the 2θ of 6.181° corresponding to d-spacing of 14.286 Å. The consequence of XRD, showed that the crystalline structure of was significantly altered by grinding. Meanwhile, the variations of particle size and surface characteristics were also investigated using SEM analysis.
