Abstract: The phase composition and morphology of Al2O3 powders after different heat treatments andthe influence of the characteristics of the Al2O3 powder on sintering performance of Na-β"-Al2O3were investigated. The experimental results showed that the denee β"-Al2O3 ceramics can beobtAlNed only from α-Al2O3 starting materals.

Key words: Al2O3 powder, powder characteristics, Na-β"-Al2O3 ceramics
