| Abstract: | The influence of the Na2O/Al2O3 mole ratio in sodium aluminate, the pH and the temperature of precipitation upon physicochemical properties of pseudoboehmite obtained from sodium aluminate has been studied. A mole ratio of 1 1 and low pH are favorable for the preparation of pure alumina.
