New members of a family of layered bismuth compounds

Two new compounds, Bi3Ti2O8F and PbBi3Ti3O11F, were prepared and identified by X-ray diffraction analysis. These compounds are members of the family called layered bismuth compounds. Thermal properties of the new compounds were also studied. Besides the preparation and identification of these new compounds, a new method for preparing already known members, Bi2NbO5F and Bi2TiO4F2, was reported. Moreover, the possibility of the existence of other new members belonging to the family was discussed.
