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