Оба видео про тмдд на месте и доступны через плейлист. Ну а это вещество очень мощное, сравнимо наверное с комплексами нитротетразола. Скорость детонации порядка 8000м/с, но эго особенность не столько в мощности а в очень быстром перезоде горения в детонацию. Вообще посмотри лучше 2 видео Дугана Эшли, я их тоже в плейлист запихал вместе со своим. Он рассказал практически всё что известно на данный момент по жтому веществу.
Проще всего конечно на ибее купить, дороговато проавда. Но вообще получаеться довольно просто. Сначала жаришь мочевину с оксидом кальция, получаешь цианат. Потом цианат жаришь на костре в банке с дыркой получаеться цианамид кальция. Потом цианамид в воде при контроле pH с гидразин сульфатом даёт аминогуанидин. Это самый простой способ на ютубе есть куча видео по нему.
This is similar to 'Cocoa Powder'...a sulfur-free gunpowder used by the French Army. Potassium nitrate and lightly charred grape-vines. The product has a light brown color, hence the name. Sometimes called Brown or Prismatic powder.
Sulfur doesn't function like an accelerant, it functions as a discount card. Whatever can light will light for cheaper energy cost when sulfur is added. Doesn't work here. The activation of potassium nitrate with this preparation requires no lowering of activation cost, you'd be making the mix as unstable as a ZnS micrograin mix. There's enough oxidizer and fuel, and there's no issue with initial activation. If you want an accelerant while mucking around with sannadex (That's what you're making here) you want fine-mesh aluminium powder (light works well, have not personally tested dark). This is what will dramatically increase the burn rate. 1-1.5%, added like the rust. In rocketry, aluminium trades burn time for dramatic increase in burn speed / peak pressure. Pressure risks cause explosion risks. Mind your fingers and your face.
@@mrhappyface4181 I can only say that one knows only when one tries, sulfur role might be very complicated in pyrotechnic mixtures , usually connected to different phenomena like - a flux, a fuel, an oxidizer, it can react with organic matter to generate H2S therefore gas transport reactions, it can make acidic gases thus helping nitrates to react easier, it can bind with metal ions freeing up more oxygen, etc,etc... So exact effects on speed of reaction can only be seen experimentally.
@@papanyanz You aren't using it to make gasses, it isn't used as a fuel, it isn't used as flux, the acidic excretions destabilize the mix and make it incredibly unsafe for storage, and KNO3 doesn't require the activation discount to free up O2. Sulfur can be complicated. However, here it isn't. It just ends up grabbing to the sugar, burning slowly, and smelling awful. Experiment away, and get back to me. If you can find a practical use for sulfur addition to KNO3/Sugar mixes: I'd be happy to listen.
@@papanyanz None of them mix sulfur and sugar. I guess the guy you read isn't intellectually impaired. Try to imitate that, if you're not capable of naturally replicating such a phenomenon.
Take care with armstrongs mixture. THe more pure the source chems, the more reactive. If you take lab grade chlorate and phosphorus, it can be set off by simpy touching it when fully dry. I know, stupid safety police comment. Just thought it would be good for others that may copy this with more pure chems than you get from breaking down safety matches.
does the grain size of the smoke mix make any difference in the combustion? I see that yours has bigger grains, but would it work with a fine powder form?
also, does the kind of tape matter? I've used electric tape on a weaker mix, but I see you're using masking tape and would it matter how tightly I wrap the ball?
In theory should be good. Crimson powder when it hot is not liquid so its hard to pack to rocket motor. One dude made small nozzleless rocket motors from it.
to grind lumps into a powder take a glass cup with concave bottom, press it down into pile of hard lumps, then move your hand in circular motion while continuing to press downwards the circular motion for some reason obliterates super hard lumps, but its important the cup is concave so it concentrates the pressure along with the circular motion as chemist ive dealt with lumps for many years, coffee grinder, redissolving, hammer etc, but the cup+circular motion breaks anything
Update: I messed up my crimson powder in this video. Its burning is dirty. Yellow iron oxide is not a good catalyst, use red iron oxide 1-2%. I explained everything in this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3dYPa_shwNA.html
You could try adding a bit of carbon, as making the mixture darker can let it react more quickly by absorbing heat to initiate further reaction efficiently (one big advantage of black powder). Ofc oxygen balance should be adjusted to still be optimal.
В общем, в статическом тесте, т.е. насыпью: Cr2O3 эквивалентен Fe2O3, но некоторые гранулы не подожглись и разлетелись в разные стороны. С Ni2+ больше похоже на карамельное топливо, чем на вышибной состав. MnO2, Co2+ также не показали хороших результатов. Из оксидов железа лучше всего себя показал смешанный оксид Fe3O4. На меди отлично себя показывал состав (добавлял гидроксокарбонат в качестве катализатора), даже быстрее был, чем на железе 3+. Только вопросы к стабильности при хранении - вероятно, медь 2+ будет восстанавливаться аскорбинкой до меди 1+ при изготовлении, но на воздухе медь +1 не то, чтобы устойчива. Так что трудно спрогнозировать, насколько хорош будет "полежавший". Замена катализатора углём с добавкой нитрата до стехиометрии, как ни странно, почти не добавляет искр, а сгорает примерно как с оксидом железа 3. С ПАП горит быстро, но в некоторых местах температуры хватает, чтобы прожечь бумагу На сере вместо катализатора не так резво горит, как с Fe2O3, но безсопловик, в котором я попробовал использовать его в качестве ракетного топлива, взорвался на старте, чего не происходило с МП
I'm afraid that its impossible to make BP substitute without potassium or at least sodium nitrate. If you can't buy it then need to make it by yourself.
@@brocktechnology Apart from various conversion methods you can actually make your own calcium/sodium/potassium nitrates from scratch "at home" if you have access to living soil and urine :-)
@@NinjaChemistChannel Would Ammonium Nitrate (I have 300g of 99.9% industrial fertiliser from a local farm for adding to my garden) work at all? I know that decomposes and is nasty (the recent Beirut explosion showed that)
Maybe the yellow iron oxide is converting to black iron oxide where as using black iron oxide gets converted to red iron oxide to make it "crimsen" Maybe just jibberish...
In the United States, a minor variant of this formula has been commercially available as American Pioneer Powder, sold for muzzle-loading guns. Reports are that it doesn't form hard fouling with conventional petroleum-based bullet lubricants like actual black powder or Pyrodex will. The American Pioneer Powder container doesn't contain any warnings about hygroscopicity -- but whether that's because they've created a version that's less prone to pull water out of the air, or just don't bother to warn buyers, I can't say. I have a can of it that's several years old; I loaded some cartridge ammunition from it and closed it tightly; I should see if it's still good.
Sodium salts are much less hygroscopic than Potassium salts. I wonder if the difference between crimson powder and American Pioneer Powder, as far as hygroscopicity, is the oxidizer used.
I tested the hygroscopicity of my crimson powder by leaving them at room temperature for few days. Humidity was 45%. It absorbed less than 1% of moisture, so i think it can be considered as non hygroscopic, at least if it was prepared same way as in the video(same temperatures, drying at 70C e t.c.)
I have very little information, mostly speculations. According to the article: pyrosource.fandom.com/wiki/Crimson_Powder The residue on ignition is only 28% compared to about 50% using black powder. In addition, the residue from burning golden powder is water soluble, unlike many other propellants. Sulfur is bad for gun barrels, crimson powder does not contain sulfur. I don't tested it in gun since I don't have one. I've heard other people tested sugar based sulfurless BP substitutes, they used 1.5-2x bigger quantities of such powder to reach same effect that BP does, but they were very happy that It burns cleaner. Crimson powder should perform much better than sugar based BP substitutes and give almost the same power as BP charge. Thats a theory, It needs testing. Upd: one dude tested crimson powder in guns ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1irzH27Ix0A.html
@@NinjaChemistChannel hm, interesting. important if experimenting to keep in mind that copper oxide if used instead could catalyse the barrel to rusting
@@NinjaChemistChannel oh and i think if you wanna water-proof the granules, you can buy some ice fountains and dissolve in acetone, then spray dilute solution of that nitrocellulose lacquer onto the granules, it should cover the surface nicely and make it water-resistant for longterm storage, ice fountains are made of good quality NC
Yoo, He back! You say do not use induction Heater, why would this be? Is it harder to measure temperature on that? Taking in mind that you'd use a compatible pot
It heats up too fast, too effective, its like cooking at open flame. Almost impossible to control the temperature. Hot plate you heated to 200C and thats it, you have 120C at your pan, you can cook.
Ninja Chemist? Is that you? Man, you came back! Sorry I didn't notice that earlier, Life gets busy and there is no space for doing man's hoppy, you know what I mean 😅
Неплохо себя также показывает жёлтая версия, на аскорбате калия (натрий брать не рекомендую, гигроскопично получается). Т.е. гасится аскорбиновая кислота карбонатом калия по стехиометрии, и дальше по технологии
