Mechanochemistry Fireworks

What kind of fireworks do you mean. Do you mean classic batteries of salutes flying out of mortars?

@argentum Yes, probably. The ones for the sky launch 

@chaoticgood There are at least 2 main types of pyrotechnic compositions used in these products: expelling, which is used to eject the projectile from the channel of the mortar, and explosive, which directly scatters the projectile itself and its pyrotechnic elements burning in the sky, called stars.

Knockout compositions are usually black powder or its modifications, that is, they consist of potassium nitrate, sulfur and coal Disruptive compositions should already be sharper and have greater energy, therefore, perchlorates (potassium perchlorate) are used with or without potassium nitrate and aluminum as a reducing agent or its alloys with magnesium (magnalium)

Colored flame pyrotechnic compositions already contain various flame-coloring ions. Often, red compounds based on strontium nitrate or carbonate, green-barium nitrate, yellow-sodium nitrate or cryolite, blue-insoluble copper compounds (for example CuO, Cu₂Cl₂, (CuOH)₂CO₃) and chlorine-containing substances. Magnesium or magnesium is often used as a reducing agent, but organic substances can also be used.

@argentum Oh, so it's like a child of gunpowder?

@argentum *-* Cu2Cl2 is an unexpected candidate in the list. I always thought that compounds of Cu(I) aren't very stable

@chaoticgood Didn't understand you "child of gunpowder"?

@chaoticgood Cu2Cl2 is stable, besides it is insoluble in water

@argentum Gunpowder have the same composition 

@chaoticgood Well, I said that it is black powder and used there, there can only be small variations in the ratio of components

@argentum So the actual gunpowder then?

@chaoticgood yes
