## Synthesis

Bismuth titanate ceramics can be produced by heating a mixture of bismuth and titanium oxides. Bi12TiO20 forms at 730–850 °C, and melts when the temperature is raised above 875 °C, decomposing in the melt to Bi4Ti3O12 and Bi2O3.[4] Millimeter-sized single crystals of Bi12TiO20 can be grown by the Czochralski process, from the molten phase at 880–900 °C.[1]

## Properties and applications

Bismuth titanates exhibit electrooptical effect and photorefractive effect, that is, a reversible change in the refractive index under applied electric field or illumination, respectively. Consequently, they have potential applications in reversible recording media for real-time holography or image processing applications.[4][1]
