Hello fellow pyrotechnicans, i just wonder if anyone could help me with a guide how-to-make for example Strontium peroxde?

Cheers

I'm afraid that burning Sr metal in an oxigen atmosfere is not quite the cheapest way to make it, but unfortunatelly it may be the only practical way.

Also, if we talk about these burning methods, you can by theory Melt Strontium in a test tube and bubble the molten metal with pure oxygen gas.

Cheers

Here is the synthesis I have. Strontium can probably be substituted for the barium.


Barium Peroxide

Preparation: Prepare a solution of 47g of barium chloride dihydrate in 250ml water. To this solution add 250ml 30% H2O2. Add 200ml 24% aqueous ammonia solution with stirring. Let the mixture stand until no more precipitate forms. Decant the clear portion, and replace the liquid with fresh water. Repeat the decanting 2-3 times. Filter on a Buchner funnel and wash with water. Dry in a porcelain cup at 50-70°C, occasionally spreading the powder with a spatula. After the product turns into a crumbly mass, increase the temperature to 75-80°C. Store the completely dried product in a tightly sealed bottle. Yield: 55-60g of the octahydrate. The product can be further dried to the hemihydrate at 130°C. The completely anhydrous peroxide can be obtained above 200°C, but a partial loss of oxygen will occur.
