What is the best oxidizer for flash powder?

Potassium perchlorate
Potassium perchlorate is the most commonly used oxidizer in colored pyrotechnic compositions and flash powder. It’s also used in whistles, strobes, waterfalls and many other pyrotechnic devices.

What is the most stable flash powder?

Strongest and SAFEST flash I know of is 70/30 KClO4/Al. Make sure the Aluminum has the smallest particle size you can find, along with the Perc. Smaller particle size translates to faster reaction.

What is the best flash powder mix?

This composition, usually in a ratio of 5 parts potassium nitrate, to 3 parts aluminum powder, to 2 parts sulfur, is especially popular with hobbyists. It is not very quick-burning unless exceptionally fine ingredients are used.

What are the ingredients in flash powder?

Flash powder is a rapidly-burning mixture of an oxidizer and a fuel—commonly potassium perchlorate and aluminum powder—and is guaranteed to light things up.

Is potassium nitrate good for flash powder?

Nitrate and magnesium Potassium nitrate or sodium nitrate can be used with magnesium powder as a moderately powerful flash powder. The bang from these compositions is not as sharp as those from chlorate and perchlorate based mixtures.

Can you use ammonium perchlorate for flash powder?

Ammonium perchlorate is also used in composite rocket propellants, including the propellants used in the solid propellant boosters used for the space shuttle. The decomposition products of ammonium perchlorate are all gasses that are very beneficial for rocket propellants.

How much flash powder is in a M-80?

The tubes often hold approximately 2½–3 grams of pyrotechnic flash powder; one source states that an M-80 has at least 3 grams of powder. Some contain up to 5 grams or more.
