Barium Oxide: Properties, Processing, and Applications ...

Barium was first isolated in 1808 by Humphry Davy through an electrolysis method he devised [1]. Barium oxide, also known as baria, barium monoxide or oxobarium (IUPAC nomenclature), is a yellowish-white non-flammable material. It has the chemical formula BaO and it is also hygroscopic, which means it readily absorbs moisture from the air.
