Abstract

Al₂O₃/LiTaO₃ composite ceramics were fabricated by using hot-press sintering process in N₂ atmosphere. Effect of grain sizes of A1₂O₃ second phase and LiTaO ₃ matrix on domain structures in Al₂O₃/ LiTaO₃ composite ceramics were investigated. The results show that the domain quantity and density significantly decrease with decreasing grain sizes of A1₂O₃ and LiTaO₃, and the domain zones are also enlarged. Typical non-180° domain structures are only formed in zones of bigger grain deformation, but domain type and morphology exhibit no change in composite ceramics.
