Abstract
β-Alumina has been prepared by the thermal decomposition of a mixture of sodium and aluminium isopropoxides followed by heating up to 1000° C. It has been found necessary to use sodium isopropoxide in excess (25-30%) for the complete formation ofβ-alumina at 1000° C. On the other hand one obtains a mixture ofβ-alumina andα-alumina when the starting materials are taken in the stoichiometric ratio Na2O:11Al2O3. DTA, TG and DTG studies of a mixture of sodium and aluminium isopropoxide showedβ-alumina formation at 1000° C.
