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.
This white solid (gray when impure) is one of the most common inorganic peroxides, and it was the first peroxide compound discovered. Being an oxidizer and giving a vivid green colour upon ignition (as do all barium compounds), it finds some use in fireworks ; historically, it was also used as a precursor for hydrogen peroxide .

Barium carbonate is the inorganic compound with the formula BaCO 3. Like most alkaline earth metal carbonates, it is a white salt that is poorly soluble in water. It occurs as the mineral known as witherite. In a commercial sense, it is one of the most important barium compounds. [5]
The intermetallic compound BaAl 4 is produced first: [9]: 3 3 BaO + 14 Al → 3 BaAl 4 + Al 2 O 3. 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 ...
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water. It occurs in nature as the mineral barite, which is the main commercial source of barium and materials prepared from it. Its opaque white appearance and its high density are exploited ...
