ANSU/Sugar dynamon

TheOddEngie - 18-1-2014 at 09:43

I recently came across a youtube video of someone detonating an 85/15 ratio of ammonium nitrate and sugar which was set off with just a blasting cap containing a few gram of acetone peroxide I went to look into this but couldnt find much information on the matter could anyone shed some light on things like if it really is as cap sensitive as the video I watched and how someone would go about creating the mix and since I have my doubts on the sensitivity I would treat the prills first then blend both the AN and sugar to a fine powder and mix
can anyone confirm?

I initiated it with 1-1.5 g AP or HMTD. Results are quite similar to the detonation. Charges cut trees and made holes steel plates.
The density of peroxide was 0.9-1.0 g / cm 3. The detonator is always done with the "cup" (I do not know how it is properly called in English).
Dry AC and sugar.
First, grind the sugar using a electric coffee grinder. Then grind portions AN and immediately intervene in sugar. Then the mixture was again mixed up in a coffee grinder.
Here is an example

Thank you for the nice test. Do you recommend mixing with water to aid uniform mixing? Do you have observations on the storage stability?

was that really you? watched your video +10 times in that case

anyhow ANSU aka sugar dynamon is OB with 72.7 / 27.3 mix

i recall 'fesss83' using 95 5 ANSU as sugar dynamon, but i dont recall him using and special detonator.. just a few grammes of AP

another thing: add 1g Fe2O3 per 100g ANSU, this will increase sensitivity towards shock

About the water I do not know. My opinion is that it is unnecessary complication.
Composition I kept a maximum of two days. During this time there was no change.
The mixture is quite hygroscopic.

Poorly understood why 0B is 72.7 / 27.3?
C12H22O11 + 24 [O] = 12 CO2 + 11 H2O 342g x1 = 342g
NH4NO3 = N2 + 2H2O + [O] 80g x24 = 1920g
= 15.1% sugar + 84.9% AN

Unknown whether it makes sense in the catalyst. I have not seen experiments wherever shows how iron oxide helps detonation. ( Would be great to check it.

Etanol how did you stand only 12m away from the ammonal charge (3kg?) in one of your other videos????

correct, using a fellow members calculator i found 84.9 15.1 to be perfectly OB
no wonder not all of the guys AN went off if he used excess sugar..

anyhow metaloxide sentisizers are used for explosive targets (i actually cant remember the name of the composition right now)

CuO is said to work, although Fe2O3 should do about same thing.. i think its harder to get some results as you would need to perform the same blast with a very accurate blasting cap that could be adjusted to give off less power to see how much power would be needed with / without, perhaps critical diameter would explain sensitivity with/without metaloxides?
still would be not quite the average job to do

IIRC some chromium oxides and salts are quite a catalysts, but the mixtures are unstable and not recommended.

Fantasma4500 - 21-1-2014 at 11:12

downright unstable?
how unstable.. unstable to the point of primary properties or just spontaneous combustion followed by slow deflagration?

i recall potassium ferrocyanate with ammonium dichromate as being a very violent catalyst making it decompose with high speed, as i tried this myself i realised there was a slight amount of NOx in it by smell and by NH3 forming smoke with the gas, although i didnt have potassium ferrocyanate
