Study of the BazTiO4-BaTiO3 interface (samples C) On the sample sections, after treatment~ transfor- mations are observed on both sides of the interface and near it. In the Ba2TiO4 pellet, the ortho- titanate transformed into metatitanate. In the BaTiO3 pellet, the changes are more distinct (Fig. 6).
