摘要：
A new alumina matrix composite has been synthesized via in situ reactive sintering of Al2O3 and BaZrO3 powders. Phases formed in situ were Ba-beta-Al2O3 (BaO(.)7.3Al(2)O(3)) (a so-called hexaaluminate compound) with a layered beta-Al2O3 structure and monoclinic ZrO2. The Ba-beta-Al2O3 phase exhibited an elongated morphology, while ZrO2 was primarily present in an equiaxed form. Composites of Ba-beta-Al2O3, ZrO2 and alumina encouraged crack deflection and crack bridging, thus improving the mechanical properties beyond those of monolithic alumina. The alumina-based composite with 30% Ba-beta-Al2O3 and ZrO2 showed an optimum combination of mechanical properties: high strength, large work of fracture, and improved fracture toughness.
