Barium Titanate Nanopowder with an Average Particle Size of 90 nm

A piezoelectric material used in capacitors, photonics, and batteries

Overview | Product Information | Related Products

Barium titanate (CAS number 12047-27-7), a pyroelectric and piezoelectric material, is applied in a wide range of electronic products, including capacitors, transducers, and optics. Barium titanate powder adopts an ABX₃ perovskite structure with polymorphs of cubic (currently available at Ossila), tetragonal, orthorhombic, and rhombohedral crystal structures.

Barium titanate has recently been involved in battery research. It is applied as a cathode and an additive in the electrolyte of Li-ion batteries. Theoretical simulations reveal that barium titanate diminishes the growth and spread of lithium dendrite on the electrode. Barium titanate offers a long cycle life to solid-state batteries, with a reversible capacity of 103.2 mAh/g over 500 cycles at 1C. When used as an additive in the electrolyte, barium titanate boosts ionic conductivity to 1.5 × 10⁻⁴ S/cm at 25 °C.
