Abstract:

29Si and 27Al MAS NMR spectra of calcined kaolin coming from different regions and kaolin calcined at different temperatures were acquired and compared. The results showed that the 29Si spectra of calcined kaolin coming from different regions were similar while the 27Al spectra were different. Calcination temperature was found to influence the 29Si and 27Al spectra of calcined kaolin obtained from the same area.

Key words: NMR, magic angle spinning, calcined kaolin
