KNO3/Sorbitol doped with Fe3O4 / Al / Prussian blue burn rate test

KNO3/Sorbitol burn rate test with formula (100mm):
Potassium nitrate (KnO3): 64.26%
Sorbitol (C6H14O6): 32.92%
Iron III oxide (Fe3O4): 0.94%
Aluminium (Al): 0.94%
Prussian Blue (Fe7(CN)18): 0.94%
Result: 5.88mm/s (0.23in/s)

Conclusion: Really high burning rate for a KNSB mix (2 times a reference mix). See others vids to compare.

what is the best rate for sorbitol - kno3?

i see a lot of vids with 65% kno3 and 35% sorbitol, but also some that say it the other way around

hmmmm just thinking...... so explosive organic compounds work that way for being nitrated, so this is that carbonated organic compounds can do the same?

I havent really get to understand why a organic nitrated compound is explosive, i think its because the fast decomposition of the nitrated bond relasig NO2, a strong oxidizer. So you sugest carbonates can work the same?

I don't want to know how it works but I known it works. Picmario has impressed me with his famous high burning rate s..t.

I've never tried lactose but it could be interresting.

[RicardoGarciaPino]

for the means of relasing oxigen, i assume. I did not knew there where salts that could do that.

BTW im trying unusal rocket fuels. Ever tried lactose instead of glucose? works better for me.

Hi Ricardo, ferrocianate increases nitrate decomposition

[RicardoGarciaPino]

anja! i got your little secret jajajaja

[RicardoGarciaPino]

why did you use ferrocianate??

[PyRex124]

I'am not enough crazzy to breath my rocket smoke !!! I've already thought to add nitrocellulose or nitrosugar in my knsb but it takes long time to prepare and it could be dangerous to cook. The best oxidizer for my hobby is ammonium perchlorate but it's expensive and hard to obtain in europa. Did you try ammonium nitrate ?

[PyRex124]

Thank you for your ultra relevant remarks.

Ok I going to test it but before I would try knsb+Al+prussian blue to verify effect of aluminium on prussian blue. What do you think about Pb3O4 ?
