...The chemical formula is Ba 2 TiO 4 or BaTiO 3 . The former is called barium orthotitanate, and the latter is called barium metatitanate, but in reality it is an ionic crystal (double oxide) consisting of Ba 2+ , Ti 4+ and O 2- , and does not have independent anions like TiO 4 4- and TiO 3 2- . The latter is better known, so we will discuss it below. *Some of the terminology that mentions "barium orthotitanate" is listed below.
