과산화바륨의 분해

2BaO2 → 2BaO + O2

개요

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.
