In case of x=0.15 composition samples, the total and grain boundary conductivity reached the highest values. On the other hand, the grain conductivity was nearly constant at x=0.15-0.35 composition samples. From the relationship between the crystal phase and the conductivity of the above stated composition samples, it is suggested that the high conductivity of the x=0.15 composition samples is very susceptible to the precipitation of Y_2O_3 whose conductivity is lower than that of Y_3NbO_7. Thus, the conductivity of Y_3NbO_7-Y_3Al_5O_<12> and Y_3NbO_7-MgO sintered bodies, which were prepared by the addition of Al_2O_3 and MgO, lower conductivity materials, to Y_3NbO_7, was measured. Their grain boundary conductivities took a figure up one place in the maximum. It was proved that the grain boundary conductivity enhances by the addition of lower conductors to the basic materials., rights: 社団法人日本セラミックス協会
