I'm milling everything dry in an improvised ball mill (peanut butter jar with #000 buckshot), than wetting the milled components with 90% alcohol to be combined and compacted into cakes. Performance-wise, ascorbic acid/KNO3 powder is said to …

KNO3 is mildly hygroscopic and wet chems and comps made with them are at risk of clumping (charcoal's another thirsty one). Dry it in the oven on a baking pan for an hour at 200-250F and mill it again. It shouldn't require days to mill KNO3 to …

KH2PO4; 0.02% MgSO4.7H2O; 0.02% KNO3; 0.01% KCl and trace elements, supplemented with 0.05% (NH4)2S04 as required for certain species and solidified with 1% agar (Oxoid No. 3). Dextrose and cellulose (Whatman's 'Chromedia' powder finely divided by ball milling for 72 hours) were incorporated at suitable concentrations as stated in the text.

English: Potassium nitrate is a chemical compound with the formula K N O 3.It is an ionic salt of potassium ions K + and nitrate ions NO 3 −.It occurs as a mineral niter and is a natural solid source of nitrogen. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter.

2 HNO3 + K2CO3 -> 2 KNO3 + H2O + CO2. Dissolve 200 g potassium carbonate in 400 ml hot distilled water in a 1000 ml beaker and add 242 ml of 50 % HNO3 in small portions to this. The solution is than standing for 3 days until crystals of pure KNO3 will precipitate. The water is than vaporised to collect the crystals.

Ball mill the charcoal and sulphur mix for about 3 hours (without adding any potassium nitrate). Add 75 parts of potassium nitrate (powdered) to the charcoal and sulphur mix in the ball mill. Also add 6 parts water to the mix before ball milling, this will dramatically reduce the probability of accidental ignition of the mixture during milling.

KNO3 was another matter. 4 hours hardly touched it. So I switched to US nickels. In 8 hours the KNO3 was very fine but the nickels had compacted KNO3 on the face and back of the coins so thick that the coins looked like little footballs in profile. What a mess! I then re milled the coins with marbles and salvaged most of the KNO3.

5 pounds of the chemicals for making blackpowder and a good article on ball milling 101 5 lbs charchol 5 lbs sulpher 5 lbs patissium nitrate and they throw in some dexiderin for 54 bucks. ... You can also make rockets out of dextrin and KNO3. This …

-If you would like to, ball mill your potassium nitrate using steel or high-alumina media. -50% Magnesium/50% KNO3 makes a pretty sweet flash powder. Ball mill the Mg and KNO3 separately for excellent results. Ask Question Be the First to Share Did you make this project? Share it with us! I Made It! Ask Question Post Comment

But for milling it needs to be as dry as possible. That said, if your KNO3 is actually "wet", then you've got other problem because it is definitely not that hygroscopic! The moisture level that causes clumping when ball milling is so low that it cannot be detected as "moist" or wet to the touch, but is enough to cause issues.

tumbler, and the KNO3 in another, and put them together for only a few minutes. towards the end of the milling. That is the safest way to go, and you will. still get good results. Don't dampen it at all while milling. After the. milling, sift out the media, put the powder in another container, add about 1-2.

I want to mix by ball milling KNO3 or Mg(NO3)2 with natural kaolinit or Feldspar or silica, is it safe to mill them? 2. What about K2SO4 with Ca(NO3)2 or Mg(NO3)2? Silicate.

Potassium nitrate is an oxidising salt in the form of a white powder which can be dissolved in water. Two variants are available to buy, both with the same chemical purity, one grade has been milled to a very fine powder, and the other is a coarse grade that is 20 - 80 mesh.

Flash Powder is a combination of an Oxidizer and a Fuel (powdered metal). Sold in two separate bottles, once mixed they are highly explosive. …. A "Type 19" or "Type 20" BATFE (Bureau of Alcohol, Tobacco, Firearms and Explosives) License is required to legally purchase, use, and store these types of explosives.

The ball mill method. 1. crush the charcoal with a hammer between two sheets of card. then Sieve the ground charcoal through a 30 mesh sieve. 2. Weigh out the charcoal, for every 100g of charcoal, add 67g of sulfur, 1/4 fill the ball mill with this mixture. Put the media in and run the mill for 3 hours.

Good, I have like 3 lbs of KNO3, just made a ball mill for Al powder. Al powder ? are you doing it with KNO3 ? Aluminum powder have a very high temperature of activation to burn or make flash powder, due to its oxide layer protection and its high boiling point. Zyklon-A. International Hazard.

High energy milling was performed in dry atmosphere using twin planetary ball-mill machine (Insmart, India) containing tungsten carbide bowl (100 ml) loaded with (KNO 3 + KI) powder mixture along with 2–4 tungsten carbide balls (∼10 mm diameter). The bowls were rotated @350 rpm.

Step 1: you first need to measure out your water and kno3. the way you do that is according to the chart, the solubility is 2.5 grams per ml at 100°c, so you divide the amount of kno3 you have by 2.5 and you then get the amount of water you need to add in ml. Ask Question.

Ball Milling Kno. I want to mix by ball milling KNO3 or MgNO32 with natural kaolinit or Feldspar or silica is it safe to mill them 2. What about K2SO4 with CaNO32 or MgNO32 Silicate. Get Price List Chat Online. Product New. Make Homemade Red Gum Black Powder.

The mill is rotated at high speed for up to 48 hours or longer. The result is a very finely powdered charcoal/sulfur mixture. (Note: for reasons which should be very obvious, the Potassium Nitrate is not mixed in with the fuel during the milling stage, unless you want to be picking bits of your ball mill out of the walls of your factory.) Ball ...

A mole of either KNO3 or KMnO4 produces 16 grams of oxygen, but a mole of KMnO4 is twice as much as a mole of KNO3. So, 79 g of KMnO4 will only release 8 grams of oxygen gas. ... Nitrate was fine but it needs a long ball milling time as compared to chlorate and permanganate so my final conclusi Chlorate is one of the most powerful solid (at STP ...

I have been trying to get my ball mill working but so far all I get is caked balls and pellets. I start with a blade grinder, just KNO3 and a 100 mesh screen. Ball mill is 6" diameter (150x150mm), half full of .690 (17.5mm) musket balls. I tried a drying box over a 60W bulb. No useful effect, more pellets after 4 hours tumble.

The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice: material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts – all these …

Ball mills o Best way for hobbyist to make good fast black powder o Easy to build or purchase yourself o Can use lead (recommended) or ceramic for milling media o Recommend getting Lloyd Sponenberg's book "Ball Milling Theory and Practice" ($19.94 at Amazon) o Using an efficient ball you can make high quality BP in less than 3 hours

KNO3 nano-particles with the diameter of about 28 nm were prepared by mechanical milling using planetary ball mill from the commercial KNO3 powder. Rotation speeds of ball mill were 0 …

Use meal-D or ball milled BP powder instead of KNO3, charcoal and sulfur. The meal-D will makeup 30% of the mixture. For the other 70%, use whistle mix with 1% iron oxide as a catalyst. Use lacquer thinner or acetone as the wetting agent.

Also, are you ball milling? an intimate mix is vital to a powders performance. I use a 3 hour milling with lead media for my propellant (BP). [Edited on 14-4-2012 by Bot0nist]

Posted 14 July 2010 - 12:58 PM. If the sulfur is pellatized, it has clay in it, usually 10%. You can dissolve them and take off the sulfur or grind them but use and extra 10% to make up for the binder. I will grind the charcoal with the sulfur separately if I am particualrly unsure of my surroundings for ball milling and just screen them ...

1. Only mill KNO3. Never use a more powerful oxidising agent. 2. Never mill colour comps. 3. Make sure you use LEAD or other non-sparking media. 4. Ensure the mill is away from the house - a garage may be best (without car!) 5. Dampen the mixture - ensure that it's damp at all times - approx. 8% water. This would mean that for 100g of
