Super flash powder - 0,4 gram Mg / NaNO3 / C

0,4 gram of a super fast flash powder unconfined. It is self-confining in very small amounts.

It is actually sodium nitrate based flash powder, not KMnO4 based.
The composition is:
55% magnesium (Mg)
41% sodium nitrate (NaNO3)
4% charcoal (C)

The explosion was so loud and bright that two of my neighbours came out and asked if it was me!


Thanks for watching!

You got a lovely reddish/orange glow with this. I wonder if you could improve that by mixing in some strontium or lithium salts in?

@RadioTrefoil

That would probably slow it down a bit. And I don't think it would do so much difference.

Would Armstrong's mixture detonate ANFO? Could it be used to make percussion caps and reloading primers? I and a bunch of good ole boys need to know in case someone gets re-elected.

@bmcgraw3840

No, AM can not detonate ANFO, you need a booster to do that. You can make detonators with Armstrong's mixture but it's really stupid because it's so sensitive.

hey Dornier335A I like what you said and you know your stuff about deflageration versus detonation. I'm a chemist check out my vids. Subscribe to me I will to you. talk soon Peace be carefull

@Dornier335A thanks friend, I tried a mixture of NaNO3 + magnalium the proportion 60/40 and I did not catch fire. Could it be that the NaNO3 had too much humidity? Balls are formed continuously and is difficult to sift Thanks for all

mate that would be better in day light

@CostraBrava

10 hours is not enough... You should ball mill it for a week or grind it with my steel plate method.

NaNO3 or KNO3 / MgAl are very fast flash powders too. I think the ratios are about

60 / 40 oxidiser to MgAl.

@Dornier335A  I bought magnalium than 350 mesh, and I ground in ball mill with steel balls for 10 hours. This combination of KClO4 / MgAl that ratios are?

Thanks for all friend

@CostraBrava

How fine is your MgAl?

KClO4 / MgAl is a very good flash powder.
