Description and Uses
Barium peroxide, is a grayish-white powder that is slightly soluble in water. Barium peroxide is a dangerous fire and explosion risk in contact with organic materials and decomposes around 1450°F (787°C). It is also toxic by ingestion, is a skin irritant, and should be kept cool and dry in storage. The four-digit UN identification number is 1449. The primary uses of barium peroxide are in bleaching, in thermal welding of aluminum, as an oxidizing agent, and in the dyeing of textiles.
Bariumperoxide is used as a hydrogen peroxide source and oxygen oxidant, as well as a bleaching agent. Its main usage has been for making hydrogen peroxide and oxygen, in organic syntheses, fabric printing and dyeing. Barium peroxide is available commercially, primarily as the oxctahydrate (which is the more stable form of this peroxide).
