N2 - Al2O3 matrix composites reinforced with Ba-Β-Al2O3 phase were synthesized through reactive sintering using Al2O3 and BaCO3 as starting powders. Dense Al2O3/Ba-Β-Al2O3 composites can be obtained by spark plasma sintering from Al2O3/BaO·Al2O3 powder, which was prepared by calcining Al2O3BaCO powder mixture. The Ba-Β-Al2O3 reinforcing phase exhibited an elongated morphology due to preferred diffusion of Ba cations. The existence of Ba-Β-Al2O3 phase as well as low sintering temperature and short holding time during reactive sintering inhibit grain growth and thus result in small grain sizes of the Al2O3 matrix.
