Bismuth titanate (Bi4Ti3O12) has great potential for applications over 400 °C owning to its great Curie temperature (TC ∼ 675 °C). But the relatively low piezoelectric constant d33 (< 8 pC/N) has restricted the practical high-temperature application. In this work, a new combination of the molten...
