Abstract
Theta alumina obtained by calcination of boehmite is studied by SEM, X -ray and electron diffraction, HRTEM and vibrational spectroscopy and compared with results obtained for gamma and delta aluminas prepared f rom the same boehmite. The structure of the theta phase derives from t he spinel one, The short- and long-range order in the three aluminas i s discussed.
