Abstract
Dehydration reactions of synthetic gibbsite (well and poorly
crystalline) have been studied by X-ray diffraction, thermal
gravimetric and differential thermal analysis. Crystallite
size oftbe ordered material bas been calculated from diffraction
line broadening of X-ray reflections and for highly
disordered gibbsite the grain size is calculated from electron
micrographs. The activation energies of dehydration of
gibbsite -+boehmite and gibbsite -+ x-AI20 3 have been
evaluated.
