摘要：

The subsolidus phase relations in the Bi4Ti3O12-Ag/Ag2O-TiO2 system were determined by means of solid-state reaction, X-ray diffraction and scanning electron microscopy. The rutile and anatase phases showed different chemistries when reacting with the Ag/Ag2O-Bi2O3, and the Ag0.5Bi8.5Ti7O27 phase can be obtained from the anatase form but not from the rutile form. In the present study the phase relations in the Bi-Ag-Ti-O system were established for the rutile form. The solid solutions TiO2SS, Bi4Ti3O12SS and Bi2Ti2O7SS were identified in the Bi4Ti3O12-Ag/Ag2O-TiO2 system and silver was found to be compatible with all three. There was no compatibility between the silver and the Bi2Ti4O11. A single-phase compound was obtained for the pyrochlore phase Bi1.55Ag0.1Ti2O6.375. (C) 2009 The Ceramic Society of Japan.
