· JVASP-11504· Ba2Ti3O8

Ba2Ti3O8 is a barium titanate ceramic compound belonging to the perovskite-related oxide family, synthesized for advanced functional applications. This material is primarily of research interest for dielectric and ferroelectric device applications, where its unique crystal structure offers potential advantages in capacitors, piezoelectric devices, and high-temperature ceramic systems. Compared to simpler barium titanate (BaTiO3), the higher-order barium titanate Ba2Ti3O8 provides alternative dielectric and thermal properties that make it attractive for specialized electronics and thermal management systems where conventional titanates may be less suitable.
