Peroxides are MUCH more dangerous than nitrates or perchlorates, when used as oxidizer in fireworks. Actually, they are so dangerous that this is
playing with your life.
Lithium peroxide can more easily be prepared than other alkali peroxides. You can make lithium hydroperoxide by dissolving LiOH in 30% H2O2 and then
allowing the water to evaporate. What remains is solid LiOOH. IIRC some hydrated form, but I'm not sure about that.
If you play around with this stuff, then be careful and do NOT make pyrotechnic mixtures with this if you want to keep your fingers and hands.
I have read stories on internet of people playing with Na2O2, mixed with some fuel and this ignited spontaneously.
I myself have done an experiment where I sprinkled some Na2O2 on paper and then allowed the Na2O2 to become somewhat humid. The paper ignited and a
very intense fire started, which was impossible to extinguish. |
