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.

A well crystallized kaolinite (KGa-1b) was milled for prolonged times with different amounts of organic molecules so as to obtain two different clay:organic compound ratios. Prolonged grinding and a higher clay mineral:organic compound ratio were found to be more effective in promoting a stronger removal than simple contact.

When kaolinite undergoes percussive grinding, pronounced changes take place in its i.r. absorption spectrum even in the earliest stages of the grinding when the lattice is not yet destroyed. In this report, attention is directed to the change in the stretching bands of the hydroxyl ions. A remarkably rapid effect on the band of the intralayer hydroxyl ions has been observed and is attributed ...
