Bismuth Titanate (Bi4Ti3O12)

Bismuth Titanate, or BTO, is a compound of Bismuth, Titanium, and Oxygen. It exhibits strong ferroelectric properties, which means it has a spontaneous electric polarization that the application of an external electric force can reverse. Furthermore, Bi4Ti3O12 has a high Curie temperature (the temperature above which it loses its ferroelectric properties), making it suitable for high-temperature applications. BTO has a unique layered perovskite crystal structure, which contributes to its electrical and thermal properties. Additionally, Bismuth Titanate exhibits piezoelectric and pyroelectric effects, where it generates an electric charge in response to mechanical stress and temperature changes, respectively. Due to its optical properties, Bismuth Titanate sees frequent use in photorefractive devices & nonlinear optical applications. Because of these properties, Bismuth Titanate’s primary applications are in ferroelectric random access memory (FeRAM), piezoelectric sensors, actuators, and as a substrate material for thin-film applications.
