Barium Titanate (BaTiO3) is most often used as a semiconductor, ... As a powder it is white to grey in colour and has a perovskite structure. It is soluble in many acids including sulfuric, ... barium ...

The columns, which are 10 nm in diameter, strain the BaTiO3 matrix by 2.35%, forcing it to maintain its tetragonal structure and resulting in the highest BaTiO3 transition temperatures so far.
