Arthur Posted April 29 Share Posted April 29 Ingredients are chosen to have a balance of effect, cost, availability and chemical compatibility. If you have barium bromate, try it. However as I've never heard of it's use there may be a disadvantage to be worked round. Does the bromate act as a halogen donor, is it like a chlorine donor? Just because you can think of another chemical doesn't mean that it's a good ingredient for commercial use. Link to comment Share on other sites More sharing options...
Crazy Swede Posted April 29 Share Posted April 29 Both bromine and chlorine can form the excited monohalides in the flame that we need to produce good blue, green and red flames in pyrotechnics. Bromates form as sensitive compositions as chlorates and the same incompatibilities and safety rules apply. I suppose barium bromate would work well but I have only read about the use of copper bromate for blue flames. https://sci-hub.yncjkj.com/10.1002/prep.201500231 1 Link to comment Share on other sites More sharing options...

Arthur Posted April 29 Share Posted April 29 Consider that some compounds "must work well" because the end product needs it, other end products are made down to a price because the buyers want it cheaper. The cost of the ingredients is a big part of the final article's selling price in business. 1 Link to comment Share on other sites More sharing options...

Thanks for remind me cost, availability and other things I also tested potassium bromate bluebut I am listening first time that it is used to produce whistle. As per my contact they are using potassium perchlorate, sodium salicylate and potassium benzoate whistle. Other version is barium nitrate based whistle in which there are holes drilled to fountain tube. Link to comment Share on other sites More sharing options...
