Abstract
The Aurivillius phases Bi7Ti4NbO21, CaBi8Ti7O27, and SrBi8Ti7O27 were synthesized by solid-phase reactions. The results of high-temperature X-ray diffraction and thermal analyses of certain Aurivillius phases are presented. Principal regularities of thermal expansion of the synthesized compounds are established. A correlation between the Curie temperature and the structure of the compounds was found.Keywords
