Inorganic Materials Aims and scope

Abstract

The conditions of Bi2Ti4O11 formation are studied. It is shown that the process is diffusion-controlled and depends significantly on the heating rate. The optimal conditions for producing Bi2Ti4O11 ceramics are determined. Cold pressing of Bi2Ti4O11 ceramic powder at high pressures is shown to influence the unit-cell parameters and volume, positional parameters of Bi and Ti, and bond distances in the ferroelectric ceramics produced by subsequent sintering. The ferroelectric transition temperature decreases steadily with increasing densification pressure.
