Decomposition of Barium Peroxide

2BaO₂ → 2BaO + O₂

Visão geral

Barium peroxide decomposes when heated above 700 C to form barium oxide and oxygen gas. This reversible reaction was historically used in the Brin process for commercial oxygen production before the development of air liquefaction. Barium peroxide absorbs oxygen at ~500 C and releases it at ~700 C.

Exemplo do cotidiano

Before modern air separation, barium peroxide cycling was one of the few ways to produce pure oxygen commercially.

Importância industrial

Embora o processo Brin esteja obsoleto, o peróxido de bário ainda é utilizado em pirotecnia como oxidante e em geradores químicos de oxigénio para sistemas de oxigénio de emergência.
