Abstract

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.
