Barium oxide, also known as baria, is a white hygroscopic non-flammable compound with the formula BaO. It has a cubic structure and is used in cathode-ray tubes, crown glass, and catalysts. It is harmful to human skin and if swallowed in large quantity causes irritation. Excessive quantities of barium oxide may lead to death.

BaAl 4 is an intermediate reacted with barium oxide to produce the metal. Note that not all barium is reduced. [9]: 3 8 BaO + BaAl 4 → Ba↓ + 7 BaAl 2 O 4. The remaining barium oxide reacts with the formed aluminium oxide: [9]: 3 BaO + Al 2 O 3 → BaAl 2 O 4. and the overall reaction is [9]: 3 4 BaO + 2 Al → 3 Ba↓ + BaAl 2 O 4

Barium peroxide arises by the reversible reaction of O 2 with barium oxide. The peroxide forms around 500 °C and oxygen is released above 820 °C. [1] 2 BaO + O 2 ⇌ 2 BaO 2. This reaction is the basis for the now-obsolete Brin process for separating oxygen from the atmosphere. Other oxides, e.g. Na 2 O and SrO, behave similarly. [4]
Lanthanum barium copper oxide, or LBCO, is an inorganic compound with the formula CuBa 0.15 La 1.85 O 4. It is a black solid produced by heating an intimate mixture of barium oxide, copper(II) oxide, and lanthanum oxide in the presence of oxygen. The material was discovered in 1986 and was the first high temperature superconductor. [1]
Barium hydroxide is a chemical compound with the chemical formula Ba(OH) 2. The monohydrate ( x = 1), known as baryta or baryta-water, is one of the principal compounds of barium . This white granular monohydrate is the usual commercial form.
Like all soluble barium compounds, barium nitrate is toxic by ingestion or inhalation. [8] Solutions of sulfate salts such as Epsom salts or sodium sulfate may be given as first aid for barium poisoning, as they precipitate the barium as the insoluble (and non-toxic) barium sulfate. Inhalation may also cause irritation to the respiratory tract.
