TiO₂を添加したBaTiO₃多結晶体における液相生成と直流導電率

抄録

The amount of liquid phase was estimated as the degree of change in electrical conductivity around the eutectic point in TiO₂ added BaTiO₃ polycrystalline bodies. The electrical conductivity changed gradually in the undoped specimen. On the other hand, a striking change of electrical conductivity occurred around the eutectic point in TiO₂ added specimens, proportionally increasing with the amount of added TiO₂, namely, the generated liquid phase. Accordingly, it can be said that the measurement of electrical conductivity around the eutectic point is an effective way to determine the amount of liquid phase during heat treatment.
