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.
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] In another obsolete application, barium peroxide was once used to produce hydrogen peroxide via its reaction with sulfuric acid: [3] BaO 2 + H 2 SO 4 → H 2 O ...

Barium hydroxide can be prepared by dissolving barium oxide (BaO) in water: BaO + H 2 O → Ba(OH) 2. It crystallises as the octahydrate, which converts to the monohydrate upon heating in air. At 100 °C in a vacuum, the monohydrate will yield BaO and water. [3] The monohydrate adopts a layered structure (see picture above).
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 vapor is condensed and packed into molds in an atmosphere of argon. [9]: 3 This method is used commercially, yielding ...

The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
Barium carbonate is widely used in the ceramics industry as an ingredient in glazes. It acts as a flux, a matting and crystallizing agent and combines with certain colouring oxides to produce unique colours not easily attainable by other means.
