Decomposition of Barium Peroxide

2BaO2 → 2BaO + O2

概要

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.

日常の例

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

産業上の重要性

ブリン法は廃止されましたが、過酸化バリウムは現在でも花火の酸化剤として、そして緊急酸素システム用の化学酸素発生器で使用されています。
