WebMay 1, 2000 · The gibbsite coatings which characterize the early stage of the alteration of the biotite crystals have not been observed elsewhere in our saprolite and soil profiles, either by optical microscopy or by SEM. Although feldspar weathering in some of these rocks could be a source of aluminium and the allochthonous origin of Al cannot be discarded ... WebSep 17, 2024 · The transformation of gibbsite to α-alumina occurs in the range 1100 to 1300°C. The higher the calcination temperature, the larger the crystallites and this leads to abnormal grain growth. The main goal of this research was to reduce the transformation temperature of gibbsite to α-alumina by reducing the gibbsite particles size.
