| Abstract |
| Thermal dehydroxylation of Bayers alumina has been studied by DT A, thermogravimetry,
microscopy and X-ray. Giving due consideration to the mechanisms suggested by
previous workers and based on the experimental observations made in this study, it is suggested
that aluminium tri-hydrate (gibbsite) breaks up in the first instance to mono and dihydrates
which subsequently transform to cx.-alumina through a series of intermediate phases. |
