Description

Numerous layered compounds are found to exist in the system Bi4Ti3O12-Bi2WO6. Many of them have the mixed-layer structures built up as ordered stackings of perovskite-like fragments of different thickness interleaved with Bi2O2-sheets, which can be described by a general formula (Bi2O2)(Am-1BmO3m+1)(Bi2O2)(An-1BnO3n+1). Single crystals of two these compounds, Bi6Ti3WO18 and Bi10Ti3W3O30, are grown and proved to be ferroelectric with the Curie points 750 and 735 0C, respectively. In conclusion, some peculiarities of symmetry and phase transitions of similar layered crystals are discussed. (author)
