8 BaO + BaAl 4 → Ba↓ + 7 BaAl 2 O 4. The remaining barium oxide reacts with the formed aluminium oxide: [9]: 3 BaO + Al 2 O 3 → BaAl 2 O 4. and the overall reaction is [9]: 3 4 BaO + 2 Al → 3 Ba↓ + BaAl 2 O 4. Barium vapor is condensed and packed into molds in an atmosphere of argon. [9]: 3 This method is used commercially, yielding ...
