CountZero Posted November 27 Posted November 27 Well, its not that hard to separate. Especially if you are only interested in the perc, in that case you can just use the rest as fertiliser. You can always join their discord if you have questions.

Most people have trouble separating the two, and this significantly reduces customers. The price doesn't match with this mixture idea, at least it looks like the KClO4 is being saved a lot from the mixture. For a beginner, he have no idea when it would be clean. Personally, if I were a beginner, I would rather try to buy cheaper perchloric acid and not take the risk. Most people don't bother with something if it's too complicated. But really, if this is the idea, it's not bad. However, I wouldn't put the KNO3 obtained this way into a ball mill to make black powder. Plus positive point the webshop Discord community. KClO4 is a sought-after shortage product. The beginners I talked to didn't even know about the pyro liquid mixed with water. And since it's available there, I told everyone who asked me to try it buy there, and if there is a problem, let me know.
CountZero Posted November 27 Posted November 27 I think the product as is with gd would probably make pefectly usable flash, which I guess 95% are going to use it for anyway(+- 5%).
Wilqu Posted November 27 Posted November 27 I wouldn't buy this ''KNO4'' because in the end you don't know what's in there. I would like to order one day if this store turned out to be legit is this ,,pyroliquid” with water and KCLO4, it would be enough to recrystallize and you kind of have perchlorate (I think). But for now I'm not going to order...

If it is contaminated with nitrates, it should be protect the aluminum with H3BO3. Mixed with KNO3 if not separated it won't be the same. Ba(NO3)2 Mg S are alternative in some firecrackers salutes, KClO3 anyone who can clean a KNO3+KClO4 mixture can make this at home, which is also an alternative. Using Ba(NO3)2 30 KClO4 30 Al 30 10S are a know cheaper option. Ba(NO3)2 are much more stronger any flash powder than KNO3. For flash powder this is not worth it. If I filter the water and dry the pure KClO4 crystals, it's all good for everyone. If it is crystallized once in 316g/l water. And a second time the KClO4 as a hot saturated solution once again more than 134g/l water, then the KClO4 will be quite pure. But I'll give a tip. NaClO4 very soluble in water, and the authorities can't get involved if a 40% solution are made. This is good for KClO4 and NH4ClO4 too. For KClO4 could be proportional to the quantity ordered adding KCl if the costumer required KClO4. The webshop could try this idea on a small scale. NH4ClO4 is also a shortage product.

But for now I'm not going to order... The webshop is an officially registered company. KClO4 ,,pyroliquid” have a correct price. And there will be minimal KClO4 dissolved in the solution. There is no better solution for everyone. You heat it in a bad pot on a gas stove to dry and it's done. It's not a new company, but based on the majority's feedback, it's worth buying from them, but there are significantly more reliable webshops than them.
Kalifireworks Posted November 29 Posted November 29 (edited) "Potassium pernitrate" is a mixture of 60% Potassium Nitrate and 40% potassium Perchlorate... Its a really idiotic thing to be honest and I dont know how the seller expects this item to have a use in pyrotechnics. The Potassium perchlorate/Water makes aloooot more sense than this useless white powder. Edited November 29 by Kalifireworks
Arthur Posted November 29 Posted November 29 An established fact is that most time-established pyros know the properties of most chemicals and know whether or not there are incompatibilities. Once a new compound comes on the market someone has to determine the incompatibilities -and that often happens by unfortunate accident. This compound may be real, it may be a genuinely legally acceptable to trade privately, BUT no-one actually has any facts about it's use, reactions, stoichiometry, safety, toxicity and so on...... BP may have 1000 years of manufacture, testing and use, powder made with this new chemical has no history. They thought chlorate could replace nitrate in BP once then lots of people discovered the chlorate-sulphur problem -some with personal harm. I'm open to new things coming to market, BUT 1/ they need to be tried and tested, 2/ they need to pass the precursor rules or the rules will change to name them.
CountZero Posted November 29 Posted November 29 Actually, it might have some as is for rocket fuel: https://www.nakka-rocketry.net/knpsb.html

HOWEVER their systems usually entail a multi billion test regime! Someone would have to work hard to convince me to use a new oxidiser (that's typically about 60 to 75% of a compound) without some serious research. If this stuff could exist for more than a couple of seconds which isn't likely at non-cryogenic temperatures if any, it would still only be ~55% oxygen. Lithium Nitrate is ~69% oxygen, LiClO4 is 60% if you don't count the chlorine as an oxidizer which it is, and those both exist and are produced in quantity already. Just scaling up production of something like this wouldn't be feasible until all the lithium ran out, and since the main target for this sort of thing is aerospace they'd likely attempt it with ammonium first (as I'll keep repeating, if it actually existed), which they already did, and achieved a 67% oxygen content and a zero smoke fuel that could be used in composites that could be turned on and off which are used for microthrusters in space as hydroxylammonium nitrate ([NH3OH]+[NO3]−) which has the important distinction of actually existing.
