3.1 The effect of grinding time on the kaolinite str ucture It can be found that the peaks of kaolinite in the diffractograms decrease in the strength and become wide in the shape with the increasing grinding time. This indicates that the crystallinity of kaolinite decreases and the kaolinite structure is d estroyed gradually with the grinding.

The thermal behaviour of mechanochemically treated kaolinite has been investigated under dynamic and controlled rate thermal analysis (CRTA) conditions. Ten hours of grinding of kaolinite results in the loss of the d (001) spacing and the replacement of some 60% of the kaolinite hydroxyls with water. Kaolinite normally dehydroxylates in a single mass loss stage between 400 and 600°C.
