I was checking what the knownledge of ChatGTP was regarding pyrotechnics. Well, hes still an amateur ^^
A common pyrotechnic composition that utilizes potassium nitrate is a whistle mixture. Here is a possible whistle mixture composition using potassium nitrate:
Potassium nitrate (oxidizer): 70%Charcoal (fuel): 20%Sulfur (fuel): 10%This composition can be used to create a whistling effect when it is burned. The potassium nitrate acts as the oxidizer, which provides the oxygen needed for the charcoal and sulfur to burn. The charcoal and sulfur act as fuels, which burn and create the whistling sound.When this mixture is packed into a tube, and ignited, it will burn rapidly and produce a loud whistling sound as the gases escape through the tube. Keep in mind that this is a simplified recipe and this mixture should be handled with care, as potassium nitrate is a powerful oxidizer and can be explosive if not handled properly. It should be stored in a cool, dry place, and should not be allowed to come into contact with fuels or other combustible materials.
What about a coloured composition based on AP?
Here is another possible green star composition using ammonium perchlorate:
Ammonium perchlorate (oxidizer): 80%Barium chlorate (colorant and oxidizer): 10%Aluminum powder (fuel): 5%Shellac (binder): 5%As in the previous composition, the barium chlorate is the chemical that gives the green color when it burns, it also acts as an oxidizer. The ammonium perchlorate and barium chlorate together will provide enough oxygen to burn the aluminum powder, which acts as the fuel. The shellac is the binder that holds the mixture together.Again, it's important to note that this is just one example of a green star composition, and the specific proportions of each ingredient may be adjusted depending on the desired effect, or other variations of the compounds can be used.
What about flash powder?
Here is a possible flash powder composition using potassium nitrate:
Potassium nitrate (oxidizer): 75%Aluminum powder (fuel): 25%This composition is a basic flash powder, where Potassium nitrate acts as the oxidizer and aluminum powder acts as the fuel. It is important to note that this is a very basic flash powder composition, and as such it is not recommended for any kind of use, as it may be extremely dangerous.
Flash powder based on KClO4?
A possible flash powder composition is:
Potassium perchlorate (oxidizer): 70%Aluminum powder (fuel): 20%Iron powder (fuel): 10%
I wonder where it gets its data from.
