摘要：
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.
