Energic mixtures based on lead dioxide
Some time ago I recycled lead from some car batteries and 2 jar of brown powder .
I read on internet about that stuff lead dioxide and I want to use that powder as oxidizer in some sensitive mixtures with Al powder or red phosphorus for torpedo or priming
mixtures
I need you help for some recipe based on this oxidizer.

Lead dioxide can forn sensitive mixtures with aluminim or magnesium and explodeswith a reaction like this I believe Al2+3PbO2==>2AlO3+3Pb

4 Al + 3 PbO2 --> 2 Al2O3 + 3 Pb

Ahh sorry I was thinking about AlCl3 for some reason.
Also do not use RP! That would be insanely sensitive!

Ok thanks
4Al +3PbO2 is good recipe for me and I will test it soon
Is goo ideea to add some sulfur or charcoal for more gases and explosive effect?

You would want to add in a desensitizer I think.

Sulfur and charcoal I don`t think to be a real desensitizer , anyway I work with little amount of mixture and I search for some kind of explosive
buster, more noise if you understand me
The recipe will be more helpful for me if you give it in percent %

i personally prefer cleaner mixtures. that will give u lead smoke, which could cause many health problems.

Are PbO2 mixtures really that sensitive?
I know that Pb3O4 forms very sensitive mixtures with reactive metals, just as impact sensitive as say KClO3 and
sulphur. Those mixtures also burn with very high speeds and were therefore used in dragon's eggs. I can't find much about PbO2+Al thermite though.

Finely powdered Lead dioxide and fine Aluminum powder makes a flashpowder fast thermite, as does black Copper oxide. The mix is static, shock and
friction sensitive, I would not care to handle it in any quantity. As noted, you really don't want to breath the smoke.
Your Lead is contaminated with Calcium, Bismuth and ARSENIC if it came from a modern storage battery. Nasty stuff, not a good choice for a starting
material. Sell used batteries to a scrap yard and use the money to buy cleaner materials. Even though I cast bullets and am allways scrounging for
cheap Lead, I would not use battery Lead under any circumstances.

Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

" I know that Pb3O4 forms very sensitive mixtures with reactive metals"
Chemically, red lead is Pb3O4, or 2 PbO·PbO2.
I tested a mixture with Al powder, I'm excited about it work well as impact sensitivity and noise.
"Your Lead is contaminated with Calcium, Bismuth and ARSENIC " you have right about lead but I melt it outdoor and I don`t think to be dangerous if
work with him in open space but lead dioxide powder was wash with NaClo solution and a lot of water for remove impurities and have complete oxidation

If you want shock sensitivity, there is Lead tetroxide/silicon "red thermite". It has been used as a shock to flame transducer in shock tube ignition
systems. It has also been used as a pyrotechnic hot prime, but it's more dangerous to handle than some other systems.
You might also consider purification via treating the battery plate material with an aqua regia composed of a very small proportion of hydrochloric
acid to nitric acid to obtain a Lead nitrate solution.
Remember, soluble lead compounds are very dangerous.

If you are making priming mixes with PbO2 .... I am going to assume that quantities that you will be utilizing are going to be sub-gram.
I do not see much of a difference between that and anyone who shoots recreationally. Modern cartridge primers almost always have Pb-Styphanate.
I don't know much about these mixes, having said that, unless it offers you some significant benefit compared to other mixes, as others have
suggested, I'd stay with the more tried and tested mixes.
You may be better off using the PbO2 electrodes for a Chlorate/Perchlorate cell.
