Hydrothermal crystallization of boehmite from freshly precipitated aluminium hydroxide
Hydrothermal crystallization of boehmite from freshly precipitated aluminium hydroxide was monitored using X-ray powder diffraction and FT-IR spectroscopy. Crystallite sizes and interplanar spacings for boehmite samples were determined. Changes in the crystallinity of boehmite influenced the corresponding FT-IR spectra. The maximum specific area for boehmite powder was 246 m2g-1, as measured by the B.E.T. method. With an increase of the crystallinity of boehmite, the specific area decreased and for the best crystalline sample was 91 m2g-1. All boehmite samples contained particles of colloidal dimensions. For the best crystalline boehmite sample, hexagonal-like plates were observed and some of them were elongated.
