· JVASP-57504· Ti2Bi2O7

Ti2Bi2O7 is a bismuth-titanium oxide ceramic compound belonging to the pyrochlore or related mixed-oxide family. This material is primarily of research and developmental interest for applications requiring combination of high-temperature stability, potential photocatalytic properties, or specialized dielectric performance. While not yet widely adopted in mainstream industrial applications, bismuth titanate compounds are being investigated for photocatalysis, ferroelectric devices, and advanced ceramics where bismuth's electronic properties can be leveraged alongside titanium oxide's thermal and chemical robustness.
