✦ Synopsis

The existing literature on BaTiO 3 shows that the role of the various solid solutions and phases formed as a result of 6ux additions has not been addressed satisfactorily. In particular, their in6uence on the dielectric behavior of BaTiO 3 has been largely ignored. Thus, number of criteria for the choice of a 6ux material is discussed, and an overview of the various 6ux additives that have been used in BaTiO 3 is presented. In this work, the e4ect of ZnO+B 2 O 3 and the ZnO+WO 3 6uxes on the dielectric characteristics is investigated and analyzed. Su7cient care is taken to address the e4ect of the various phases and solid solutions on the electrical and dielectric properties of BaTiO 3 . A defect chemistry model is proposed and used to explain the observed electrical properties.
