Barium Peroxide: Barium Oxide Heated in Air

Barium oxide takes oxygen from the air at about 500 °C and becomes barium peroxide; above 820 °C it gives the oxygen back. The Brin process used this to separate oxygen from air, and the peroxide was once the source of hydrogen peroxide. It is an oxidiser and harmful if swallowed.

Spread it thin

Crush the barium oxide, weigh it, and spread it thin in an open iron crucible so the air can reach it.

Heat in air

Hold the open crucible at about 500 °C in the furnace, checked with the pyrometer, stirring now and then with an iron rod. Never let it go above 820 °C, or the oxygen leaves again.

Weigh until done

Lift it out each hour, let it cool a little and weigh it. When it stops gaining, it is peroxide (step 4). Keep it in a dry, closed jar away from anything that burns.
