Barium peroxide is an inorganic compound with the formula Ba O 2. This white solid (gray when impure) is one of the most common inorganic peroxides , and it was the first peroxide compound discovered.
Barium peroxide was once used to produce pure oxygen from air. This process relies on the temperature-dependent chemical equilibrium between barium oxide and peroxide: the reaction of barium oxide with air at 500 °C results in barium peroxide, which upon heating to above 700 °C decomposes back to barium oxide with release pure oxygen.

The peroxide group is marked in blue. R, R 1 and R 2 mark hydrocarbon moieties. The most common peroxide is hydrogen peroxide (H 2 O 2), colloquially known simply as "peroxide". It is marketed as solutions in water at various concentrations. Many organic peroxides are known as well. In addition to hydrogen peroxide, some other major classes of ...
The oxidizer core is sodium chlorate (Na Cl O 3), which is mixed with less than 5 percent barium peroxide (Ba O 2) and less than 1 percent potassium perchlorate (K Cl O 4). The explosives in the percussion cap are a lead styphnate and tetrazene explosive mixture. The chemical reaction is exothermic and the exterior temperature of the generator ...
Barium, typically as barium nitrate imparts a yellow or "apple" green color to fireworks; [30] for brilliant green barium chloride is used. Barium peroxide is a catalyst in the aluminothermic reaction for welding rail tracks. It is also a green flare in tracer ammunition and a bleaching agent. [31]
The FDA has banned Red Dye No. 3 dye from food and ingested drug products. Here are the food products containing Red 3 and how the ban affects you.
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.
