So naturally, I was trying to buy potassium perchlorate online, but I only found it in a few places. And the places that did sell it were incredibly expensive ($124 for 500 grams). Are there any websites I can order from that aren't super expensive? (I don't live in the US) Is there some way I can make this salt myself? I look forward to hearing from you.
Does anybody know if it’s shock sensitive? I’m going to be using it as a smoke compound for a launched smoke bomb. I’m pretty sure it’s not impact sensitive based off of this video but I just want to be extra sure. This is the mixture I’m using.
yeah, i know. the name sounds like something this place would use as a punchline when talking about cursed energetics. the notion of using nitronium as a counterion sounds fake as shit, but evidently it is real, and is the subject of a handful of patents for rocket fuel compositions (which, uh, yeah, it's probably a very oxidize-y oxidizer).
the wiki page has nothing on synthesis, and i'm not sure how one would go about it. nitric:sulfuric + perchloric acid would be my guess but yowza that sounds like a hot gravy. anyone ever mess with this stuff? how dangerous is it? what kinds of fuels does it pair well with? does it form any other stable salts?
seems like it'd be ideal for a reverse hybrid rocket motor, if it weren't for the whole "detonation" thing. it's probably hypergolic with lots of fuels. i bet UDMH would be pretty vigorous.
EDIT: wait, perchloric acid is stronger than sulfuric or nitric. could you produce it by treating KNO3 with perchloric acid? would that kick out nitronium ions?
EDIT 2: as an additional curiosity, N2O5 is actually ionic when it's solid, and is properly named "nitronium nitrate"
Hello all, I figured I'd open a discussion thread of sorts, on the topic of Chlorate/Perchlorate toxicity given chronic, persistent exposure (such as workplace settings). It recently has come up in discussions elsewhere.
I understand that the perchlorate anion basically blocks iodine uptake, causing the thyroid to have a generally bad time. This apparently has been reported amongst people working with propellants, etc.
As for chlorates, which were once common as weedkiller, I am less sure of the mechanism of action there with regards human toxicity. They seem to stuff up your red blood cells by oxidizing them? Link.
I'd be interested to hear about case studies, etc. I'll post some ones I find in the comments below, but figure having some input from actual toxicologists and industrial safety types would be neat. Also, its quiet around here.
Note to mods: I have a few similar discussion-threads in mind, various topics from common plants to the wild world of watercolour pigments. Let me know if this kind of thread is welcome.
I've been doing some reading on the history of solid rocket propellants. I stumbled upon an article that mentioned a peculiar solid rocket propellant formulation with an average ISP of about 240, consisting of 60% ammonium perchlorate, 20% polyvinyl chloride, and 20% aluminium. It got me thinking, why did HTPB and PBAN become the default binders for solid rocket propellants? Why are other materials not used instead of these? Plastics like PVC are cheaper, for example. Plastics like polyethylene glycol have better oxygen balances than HTPB and PBAN and would require less ammonium perchlorate to oxidize them. Why aren't substances that appear to be easier to implement, easier to manufacture, and cheaper used as binders now?
potassium perchlorate: how to make
simple to make potassium chlorate by boiling bleach, cooling it, and mixing in a saturated solution of salt substitute in water. The synthesis works because potassium from the salt substitute displaces sodium from the sodium chlorate made by boiling the bleach
I'm guessing the salt substitute is potassium chloride?
for potassium chlorate l did search it up and found the exact same procedure for potassium perchlorate.
l just want a better insight from people that actually know what their doing.
Is one more powerful oxidizer than the other or nitrates are hygroscopic while chlorates and perchlorates are not hygroscopic?
Hey
Does anyone have any form of research paper on explaining Chlorate and Perchlorate Electrochemistry?
Please link it to me, briefly explain or direct me to something that might help. Thanks!

should i get the finest powder available or would that somehow negatively affect the propellant's performance. my goal is to make a fast burning propellant that also makes alot of thrust.
I’m trying to build a solid state rocket engine and I need some ammonium perchlorate for the recipe i’m doing. If any of you know websites or places I can get it in Canada let me know. Or if there are any alternatives that I could use let me know.

Exactly how dangerous are perchlorates? Could they potentially kill an astronaut is he/she inadvertently beings some into the habitat module?

What is the functional difference between potassium chlorate and potassium perchlorate in pyrotechnics? Can one do something the other cannot? I know chlorate can be more unstable to store long term, but other than that I cant seem to find anything regarding when one is the go to over the other. Thanks.
Hey guys im experimenting with different types of flash powder. And i would try to make the KClO4 - Al flash powder. Any ideas where could i get KClO4?
Hello everyone,
How do you guys source your ammonium perchlorate when building rocket motors, do you find a provider of the ready chemical, or do you make it yourself with a chemical reaction (ammoumium bicarbonate with perchloric acid)?
I read on sciencemadness that an explosive called ethyl perchlorate could be made from dry distilling barium ethyl sulfate and barium perchlorate (I think). Credits to the guy that did it, it sounds horrendously dangerous as the product - ethyl perchlorate - was a very strong and sensitive explosive. Anyone got any more information on this stuff, just out of curiousity?
Nuclear Submarines and the space station use "perchlorate oxygen candles" that produce oxygen with the chemical reaction LiClO4 → LiCl + 2 O2. Is something like ClO4- ⟶ Cl2 + O2 possible?
