Barium Titanate, BaTiO₃

Barium Titanate, BaTiO₃, has been obtained in an amorphous form by heating barium fluoroxytitanate. By heating together titanium oxide, barium carbonate, and barium chloride, brilliant, strongly refracting, yellow, cubic crystals, of density 5.91 and composition 2BaO.3TiO₂, are obtained.

A barium fluortitanate, BaTiF₆.½H₂O, is known, and also a natural silicotitanate, benitoite, BaSi₃TiO₉, in beautiful, hexagonal, sapphire-blue prisms.
