This Ossila product (M2443A1) is barium titanate (BaTiO3, CAS 12047-27-7) supplied as a white nanopowder with an average particle size of 90 nm and a purity of 99.95%. Barium titanate is both piezoelectric and pyroelectric, which is why it appears in electronic components such as capacitors and transducers, as well as in optical and photonic work.
The material has an ABX3 perovskite structure. It can exist as cubic, tetragonal, orthorhombic or rhombohedral polymorphs, and this powder is the cubic form.
Battery researchers also use barium titanate as a cathode material and as an electrolyte additive in Li-ion cells. Simulations suggest it suppresses the growth and spread of lithium dendrites on the electrode. Reported results for solid-state batteries include a reversible capacity of 103.2 mAh/g over 500 cycles at 1C. As an electrolyte additive, it has raised ionic conductivity to 1.5 × 10−4 S/cm at 25 °C.
- Development of capacitors and transducers that use piezoelectric and pyroelectric ceramics.
- Photonics research, including barium titanate nanostructures and thin films.
- Cathode material studies for Li-ion and solid-state batteries.
- Use as an electrolyte additive to increase ionic conductivity in battery research.
- Research on suppressing lithium dendrite growth at battery electrodes.
