It has been established that Bi/sub 13/V/sub 5/TiO/sub 34/ belongs to the ferroelectric family of bismuth-containing compounds with a layered compound. The formula unit Bi/sub 2/1//sub 6/ + V/sub 5///sub 6/ Ti1//sub 6/ O/sub 5/2/3 corresponds to a layered structure of (Bi/sub 2/O/sub 2/) (Bi/sub 1///sub 6/ V/sub 5///sub 6/ Ti/sub 1///sub 6/ O/sub 3/2/3)/sup 2 -/ with one perovskite-like layer between ions of bismuthyl (Bi/sub 2/O/sub 2/)/sup 2 +/. The dielectric properties indicate that Bi/sub 13/V/sub 5/TiO/sub 34/ has ferroelectric properties. The solid-phase process of formation of the compound from a mixture of the initial oxides takes place in one stage in the temperature range 600-800 C.
