Abstract

Compositions from the section Bi2MoO6-Bi4Ti3O12 of the Bi2O3-MoO3-TiO2 system were investigated by the melt quenching method. During slow cooling of the melts, a Bi4Ti3O12 phase crystallizes mainly in compositions containing above 30 mol % TiO2. In compositions with higher MoO3 content, Bi2MoO6 polymorphous crystallized. A route based on the melt quenching technique was suggested for the preparation of composite materials containing both phases, Bi2MoO6 and Bi4Ti3O12..
