is zinc dust plus sulphur dust a flash powder? if so what is the best ratio to make it burn fast as a pose to the ZN+S rocket fuel ratio. what is the purpose of ZN in this mixture? what is the purpose of S? by purpose i mean what is its job/ what does it do in this particular situation.
Help is much appreciated.IS Zinc and Sulphur dust added together a flash powder ?
Zinc-sulfur mixtures are some of the strangest flash powders that work. This mixture contains no oxidizing agent (which is normally required to provide supplemental oxygen to the reaction). This mixture only burns fast (as if an oxidizing agent were present) because the reaction of zinc and sulfur is forming only one product; zinc sulfide. Because a new product is being formed from both fuels, the reaction generates an enormous amount of heat and the reaction would continue even if there is no oxygen present. This fuel is not an example of an oxidation reaction in which oxygen combines with a fuel during combustion. Mixture ratios must allow for complete reaction of the fuels and for the most amount of heat to be generated.
