  • Abstract
    Room and high temperature X-ray diffraction, DSC, dilatometric and dielectric measurements have shown that the mixed Aurivillius phase Bi 7Ti4NbO21 presents two characteristic temperatures. The first one-close to 675°C-seems to be attributed to a ferroelectric-paraelectric transition connected with a structural change from orthorhombic to tetragonal. The second one, strongly observed by dielectric measurements concerns a possible ferroelastic-paraelastic phase transition
