Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
Barium perchlorate (Ba(ClO4)2) is a powerful oxidizing agent, mainly used in pyrotechnics.
Barium perchlorate decomposes when heated to high temperatures to liberate oxygen.
Barium perchlorate is a white solid, soluble in water.
Some fireworks may contain barium perchlorate.
Barium perchlorate can be bought from chemical suppliers.
Can be prepared by reacting perchloric acid with barium oxide, hydroxide or carbonate. The resulting barium perchlorate solution is then concentrated and cooled to recrystallize the salt.
- Make flash powder
Barium perchlorate is a strong oxidizer and also toxic if ingested.
In closed bottles, away from combustible materials.
Barium perchlorate, like other perchlorates can be reduced with elemental iron in the absence of air under UV light to barium chloride, which in term can be precipitated to barium sulfate, which has low toxicity and can be safely disposed of.
