Miech Posted November 17, 2008 Posted November 17, 2008 (edited) I recently got these compositions from someone I spoke on msn. I've tested the white and red composition with great succes sofar, and expect the yellow one to be even better from what I've heard. Name of composition: Magnesium illumination flareComposition Type: FlareCreator: unknown, I believe they are from rec.pyrotechnicsThe Compositions: Yellow 30.3% Magnesium 21.0% Potassium Perchlorate 20.0% Barium Nitrate 19.8% Sodium Oxalate 4.0% Asphaltum 5.0% Binder* White 25.5% Magnesium 34.5% Potassium Nitrate 34.5% Barium Nitrate 5.5% Binder* Red 29.1% Magnesium 19.4% Potassium Perchlorate 34.0% Strontium Nitrate 14.6% PVC 3.0% Binder* *Some such binders include: antimony trioxide, antimony pentoxide, boric acid/ sodium borate, ammonium fluoroborate, alumina hydrates, molybdenum oxides, zink borate, polyvinyl bromide, hexabromocyclododecane, pentabromobifenyl oxide, octabromobifenyl oxide, decabromobifenyl oxide etc. Any Precautions/Incompatabilities: In loose state these compositions are some kind of very bright and sensitive flash. Precautions as usual when working with flash powder should be taken therefore. The magnesium must be coated with either linseed oil or another suitable agent to prevent spontaneous combustion due to a nitrate/magnesium reaction. Magnesium is likely to react with nitrates, so keep the composition dry and do never bind with water. Do not mix or let in contact with ammonium compounds, or it will form hygroscopic ammonium nitrate. Do not look into the flame when burning, this may damage your reticula permanently! Precedure/Preparation:Drie the oxidators in an oven at 110 degrees Celsius for about an hour. Then mix the oxidators, PVC, asphaltum and/or colorants together, for example in a mortar and pestle. Then add the magnesium, and mix using the diaper method (preferred) or another low friction way of mixing. Then bind using a water free solvent, and either press into tubes or make into pumped stars. Depending on solvent you might have to work very quick. Prime very well with a very hot prime composition. I used PVC and acetone to bind these compositions, but parlon, red gum and such probably work as well. Try to avoid closing in by using a not too volatile solvent. Edit: I found out today these compositions are used by the US Navy. It might say something I guess . Edited November 18, 2008 by Miech
val77 Posted August 13, 2012 Posted August 13, 2012 whas the blinder ? and the white flar work with magnalium ?

Potassiumchlorate Posted October 24, 2012 Posted October 24, 2012 (edited) You can not make white light with MgAl - I have tested. You have to use pure magnesium. Edited October 24, 2012 by Potassiumchlorate
val77 Posted October 25, 2012 Posted October 25, 2012 a nice formula with magnaliumSodium nitrate - 48 %Magnalium (~80 mesh) - 45%Dextrin - 7 % a videohttp://www.youtube.com/watch?v=KIHh236Y_Cc
Potassiumchlorate Posted October 25, 2012 Posted October 25, 2012 It must be pretty coarse Mg in those. You could use finer and get terrific stars
val77 Posted October 25, 2012 Posted October 25, 2012 yes ! this formula is perfect for illuminating flares !
val77 Posted October 26, 2012 Posted October 26, 2012 another questionthe white magnesium flare don't have pvc or parlon or red gum ? why ?
Potassiumchlorate Posted October 26, 2012 Posted October 26, 2012 You don't need chlorine for white. PVC and parlon are there just for chlorine. White is from magnesium oxide
pyrodivision Posted April 7, 2020 Posted April 7, 2020 can i make red illuminating flare using strontium nitrate, magnesium and pvc ? i dont have kclo4
Crazy Swede Posted April 7, 2020 Posted April 7, 2020 Yes, that is what you need but I would advice you to add say +2 % of linseed oil to your composition to get a better shelf life.
