| Abstract: | BaTiO_3-based semiconducting ceramics were sintered in TE103 single-mode cavity microwave furnace. The mechanism of microwave acting on ceramic materials was studied. Meanwhile,Nb5 as donor impurity and Cr3 as acceptor impurity were doped in BaTiO3 ceramics,respectively. The results indicated that the impurities had an obvious effect on grain growth of BaTiO3 ceramics in microwave field. Based on defect chemistry,a reasonable explanation was given on the phenomenon. |
