The autoignition temperature is 590 oC.
Black powder is a traditional gunpowder made from a mixture of sulfur, charcoal, and potassium nitrate. Flash powder is a more modern pyrotechnic composition that produces a bright flash of light and a loud noise when ignited, typically composed of a fine fuel powder and a strong oxidizer. Flash powder is more powerful and volatile than black powder.
The autoignition temperature is 590 oC.
The exact coposition will vary, and in many cases is a trade secret, but flash-bang grenades DO use some type of finely powdered metal to produce the very bright flash. It could be magnesium or zirconium/ titanium/ aluminum, etc.
To combine aluminum sulfate, simply mix the required amount of aluminum sulfate powder with water in a container. Stir the mixture until the powder is fully dissolved. The aluminum sulfate solution is now ready for use.
Gray brand aluminum powder is commonly recommended for making tannerite. It is important to follow the specific mixture ratios for tannerite to ensure safe and effective results. Be sure to handle and store aluminum powder and tannerite materials carefully to prevent accidents.
It will depend on the oxidizer you are using. Nitrate-aluminum flash powders are pretty stable, but a ammonium perchlorate-aluminum flash powder is extremely shock sensitive. One scrap on the ground and it could ignite. By the way, flash powders (with the exception of ammonium nitrate and aluminum which is explosive) do not detonate; they just burn very fast.
It makes white colored stars. Its' also an ingredient in flash powder.
You cannot buy flash powder online or at any other store - that would be like buying C4 over the Internet. You would need to make it yourself from an oxidizer and aluminum or magnesium powder.
you can't buy flash powder. it is used to make firecrackers and explosives, so it is not commercially available. You can make it from an oxidiser and a metallic fuel such as KClO4 and Aluminium.

how do you separate aluminum powder and salt
The autoignition temperature is 590 oC.
Early flash powder was made of thermite. And yes, it was extremley messy and if the pan holding the flash powder wasn't held carefully could easily cover everything
Aluminum powder will sink in water because it is denser than water.
The invention of flash powder is credited to German chemist Adolf Miethe and Austrian-born photographer Johannes Gaedicke in the late 19th century. Flash powder revolutionized photography by allowing for the creation of high-speed, bright flashes of light to capture images.
No flash powder is stronger and also more unsafe! I suggest reading up on the matter if you would like to know more.
