Barium orthotitanate

It is a colourless solid that is of interest because of its relationship to barium titanate, a useful electroceramic.

[2] The structure of Ba2TiO4 is unusual among the titanates because its titanium atoms sit in a four-oxygen tetrahedron rather than a six-oxygen octahedron.

[6] Additionally, there are polymer precursor, sol-gel and reverse micellar routes to Ba2TiO4 synthesis.

[3] Ba2TiO4 has also been successfully grown as a thin film with chemical vapor deposition.

[7] Barium orthotitanate can remove up to 99.9% of CO2 from a high-temperature gas stream[10] by the reaction:
