| Abstract: | Ultrafineγ-Al2O3 particles w ere prepared by thermal decomposition of ammonium alum.Subsequently, calcining them at higher temperature, α-Al2O3 powder was obtained. It was found that the pow der, composed of α- and γAl2O3 particles, was better for sintering than pureγ- orα- Al2O3 pow der. |

| Keywords: | ammonium alum thermal decomposition ultrafine particle sintering |
