Kno3 mg flash powder Vilket flash tror ni är kraftigast, som är baserad på kaliumnitrat eller liknande lagliga alternativ. KNO3/Mg for examples has got a much higher ignition temperature than other flash compositions and isn´t too sensitive at all. Mar 19, 2006 · well the only flash powder i made is KNO3/MgAl/S in ratios of 50/30/20 and 40/30/30 in both ratios they seem the same also 50/20/30 works but i found that more MgAl works better and makes a strong POOF when lit unconfined, this stuff is obviously more better then a KNO3/Al/S mix but i dunno if better then KNO3/Mg. Dec 23, 2006 · Vandaag even een knallertje gemaakt met kno3 flash . PS. Apr 18, 2012 · And I also think there is a place for sulfur in certain flash. I'm currently making firecrackers. When using Al, a bit boric acid very well mixed with the KNO3 might be a good idea. So about: KNO3 69% Al 31% Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly (deflagrates) and produces a loud noise regardless of confinement. But when i put the kno3 in a mortar than put everything threw a 40mesh screen it makes a very deep sound and its very fast. In my opinion it would be more like this: 6 KNO3 + 10Al ---> 3 K2O + 3 N2 + 5 Al2O3. Mg shares almost no chemical similarities with charcoal or sulfur. Hier de fotos : Ik heb 12 gram gemaakt , verhoudingen van flash#5 Gewoon alles samen in de vijzel gepleurd geen gediper met deze flash , hier kan je een olifant op laten dansen zonder dat er wat gebeurd . Potassium nitrate or sodium nitrate can be used with magnesium powder as a moderately powerful flash powder. KNO3/MG is way more powerful than this mixture…but this composition is the cheapest one that you can make. I don't have much Mg/Al powder. Apr 1, 2020 · Hi! This is my first post. Aug 21, 2017 · Flash on KNO3 can be noisy / powerful enough, but KNO3 / Al alone isn't commonly used. Stoffen kunnen wel wat fijner , als je een ballmill gebruikt . [Edited on 28-11-2013 by Zyklonb] Jul 27, 2019 · Vad använder ni nu när kclo4 är förbjudet till flash? Skriv gärna vad ni använder. The chemicals are finely powdered, mixed thoroughly, and tested to ensure ignition before the flash powder is completed and ready for 4. com/pyrosuppliesuk/UK only Oct 18, 2024 · Example ballmilled, 40 μm / 400 mesh, fraction 40-4μm - 0,2%, fraction 20-40μm - 67%, fraction <20μm - 32,8%, it contains a significant amount of particles around 20 microns. Nov 29, 2016 · hi beed,the metal particle size and shape has more bearing on the speed and sensitivity of flash powders than the mesh size of the oxidiser since a particle of the metal has to melt to initiate the reaction,,well so ive read anyway im no expert here. The passivated magnesium flash powder is stable and generally safe to store. (forms a dense cloud of mg-/potassiumoxides and nitrog Apr 20, 2006 · IMHO, KNO3:Mg flash (in 50/50) is not as safe as some other flashpowders such as perchlorate/dark aluminum (70/30). 2 KNO 3 + 5 Mg → K 2 O + N 2 + 5 MgO Jan 21, 2016 · Something else i can just recommend is BaSO4/Mg flash. I think without sulfur it would form potassium oxide (not sure maybe potassium aluminate). Flash powder is a raw material and not a current pyrotechnic product. 5. I have all the materials, my aluminium powder is even everything in this video can be bought at https://www. Flash powder is a low explosive that can cause damage if confined in small amounts over 40 grams. Of course, I guess it all depends on what mesh magnesium you are using. Ratio's may differ, depending on the purpose. Here need to coat the Mg with 4% boiled linseed oil and dry it to get a hard strength coat before use or the chemicals will attack the Mg! And the NANO3 must be dried after grinded and before use at 150-200°C to get free from moisture. I have both kno3,mg flash powder and black powder, but i mainly want to make BP firecrackers because of high supply. Nitrate based flashpowders need very strong confinement to render a relatively low pitched boom. The materials should be extremely fine and dry, both the aluminium and KNO³. I need to know safety precautions, the best known ratios etc. Sulfur and acids must be avoided! Nitrate and magnesium. This document provides instructions for making magnesium and potassium nitrate (Mg:KNO3) flash powder, including weighing and mixing the chemicals in a 50:50 ratio. I have cut expensive dark aluminum with cheap spherical or bright flake for use in aerial salutes. The coarser the metal powder, the weaker it will be for flash powder. also i find that the addition of sub-micron ti powder at about 3% to 5% can help the heat of the burn thus In my experience, for various reasons, metal-oxidizer fuels tend to operate optimally (if you want fast/hot/flash) somewhere around 45-55% metal by weight, or about half. Also BaSO4 isn't hygroscopic. Skulle själv vilja testa Kno3 + Mg men har hört att det självantänder. It gives of a green flash and a deep boom, quite different to the high pitch of kno3 or perc flashes (yes i know kno3 is not as high pitched as perc, but this a much deeper sound). I do not have KClO3/KClO4, the olny oxidiser I have is KNO3. KClO3---- just don't go there, all the NH4 and S problems KClO4 flash is overall the 'safest' and is certainly the more commonly Jun 7, 2004 · Page 1 of 55 - Flash powder - posted in Pyrotechnic Formula: Alright, yes flash powder is and should be a sensitive topic, but I haven't really seen anybody hit the subject that directly on this forum, so I feel that I should start up the questions and answers. Metal fuels have other things going on than just stoichiometry, thermal conduction being one of them. In the case of KClO4 and KClO3 (without sulfur), this still can explodes loudly even though the mixture is slow and a strong much more weaker oxidizer mixture are Jul 24, 2007 · @ Marble: KNO3/Mg (or Al or MgAl) is reasonably safe if you keep the KNO3 completely dry. They often are used as booster or a prime break charge in smaller display devices. Dec 29, 2021 · This flash powder is more brisant than its perchlorate counterpart, so it gives louder reports. but I have played with kno3/mg flash and know that it cannot be stored under any circumstances Sep 29, 2019 · Ok, Here is another interesting experiment. Very pure and dry KNO3 is needed. I was wondering if any of you could give me any tipss for making small bangers or firecrackers out of a KN03 / S / Al formula. What happens when you mix aluminum powder with stump remover, potassium nitrate? it creates a very bright and ene Mar 3, 2025 · I ball milled Kno3 very fine also i passed everything threw a 325mesh screen and the Flash powder is crap. If magnesium is not a very fine powder, it can be passivated with linseed oil or potassium dichromate. Feb 23, 2013 · Potassium metal is way too reactive to be alone like that. . Make very small quantities at first, so you can appreciate the power of such mixtures. I cannot seem to get my hands on any KClO4 but I have lots of KNO3, and I want to make a powerful flash powder, comparable to a flash powder made using KClO4 and 400 mesh aluminum powder. And thats not true! Mg based flash powders are more sensitive than AL based ones. I used 2 micron from skylighter (or so it was advertised) and the flashpowder made from this proved to be very very flame sensitive. I have Mg powder, Al powder, Sulfer, sugar, fuses, and a scale. Feb 27, 2022 · NaNO3 Mg S 50/40/10 with 400 mesh fine magnesium powder. Alright, first off, I know that flash powders are to be used only in small amounts, perhaps larger amounts in mortors, but what are Aug 6, 2006 · KN03 / S / Al - Flash Powder - posted in Pyrotechnic Formula: I am relatively new to pyro and I have already tried making black powder (successfully ). KNO3 / Mg works very well, as you discovered. I need to know the science behind how both BP and FP act when being compressed or in a fluffy state, and how to create Feb 4, 2008 · With flash safety is always relative: KNO3 flash is harder to light, but is generally KNO3 and Mg, hence Mg incompatabilities are of concern. Nov 29, 2013 · Flash Powder with KNO3 I have alot of KNO3, and want to make a very fast burning flash powder. Typically it has, as you said, sulfur added. instagram. It is in the slow flash formula because it probably wouldn't light reliably without it. Even with Al its normally Al with S and then you have Sulphur problems. #stem #ramzland #wearewayne #bpeknights Potassium nitrate/magnesium flash powder should be mixed and used immediately and not stored due to its tendency of self-ignition. Oct 29, 2012 · He had assumed not only that I was only using nano3 for a substitute for kno3, but that since kno3 oxidizes charcoal and sulfur better that the same would be true for mg. Nov 3, 2023 · Homemade STRONG Flash Powder:- KnO3:50%- Mg:30%- S:20%The video was not made for invitation purposes! No one should try this at home! May 12, 2023 · Chinese firecrackers are filled with lot of sulfur in addition to KClO4 Mg/Al, and mixed with cheaper KNO3 or Ba(NO3)2 half with KClO4 or KClO3 which is why the flash powder is slow. When using less reactive aluminum, adding sulfur can again allow the flash light reliably. Do not store flash compositions, especially any containing Mg. although this flash powder Apr 21, 2017 · This little test shows a classic flash-mixture, using potassium nitrate and magnesium at a 55/45 ratio. Also, does anyone Mar 3, 2024 · Keith Ramsey explains the redox reaction between magnesium and potassium nitrate in this flash powder demonstration. The bang from I was wondering if anyone knew how a flash powder made with KNO3/Mg would compare to a flash powder made from KClO4/Al, when used for a report. Jul 24, 2007 · @ Marble: KNO3/Mg (or Al or MgAl) is reasonably safe if you keep the KNO3 completely dry. A ratio of 70% KClO 3 with 30% Al is close to the stoichiometric. Har testat Kno3, alumnium och svavel och är inte i närheten av kclo4 / al. KNO3 50% (by weight) Mg 50% It is very important to have the KNO3 very dry, if evolution of ammonia is observed then the KNO3 has water in it. wrkw orni iry cjvmwbdr cgkwf vjwgus iyhpg alfct ofowyt siuy rxtapybo wmxm nptv iizacp jpks
