Effect of Reductant Type on Phase Composition and Ferroelectric Behavior of Combustion-Synthesized BaTiO3 and Bi4Ti3O12

Finely dispersed BaTiO3 and Bi4Ti3O12 powders were prepared by solution-combustion synthesis using glycine, carbamide, and glycerol as reducing agents. The use of glycine as a reducing agent was found to yield single-phase BaTiO3 and Bi4Ti3O12 without additional heat treatment. Explored was the influence of reductant type and process parameters on the phase composition, crystal structure, and dielectric properties of combustion-synthesized barium and bismuth titanates.
