Potassium nitrate is a good source of both potassium and nitrate ions. When heated to to temperatures between 550 and 790 °C, under an oxygen atmosphere, it loses oxygen and converts into potassium nitrite: 2 KNO 3 → 2 KNO 2 + O 2. Molten potassium nitrate will react with carbon dioxide and water vapors to form potassium …

How to safely mill granular Potassium Nitrate with a blade-type coffee grinder. Make Black Powder Without a Ball Mill - Easy 1 Hour Method Make your own black powder-aka gun powder-without expensive tools or a ball mill.
Adding water to mixed black powder can cause the potassium nitrate to re-crystallize, which will reduce the power of the powder unless it's re-crushed or run through a ball mill again. If dampening the finished powder, prior to pressing into puck for corning, if just needs to be dampened a little like with an iron-board sprayer bottle.
I mill about 1/3 of the charcoal with the Potassium nitrate, and then the other 2/3 of the charcoal with the sulfur and binder. Then I screen them together. It works great, not quite as good as regular combined milling, but I feel much better about it.
Black powder is a simple mixture of powdered potassium nitrate or saltpeter, charcoal and sulfur. But simply mixing the ingredients together is not going to give you the results you are looking for. Follow …
The use of potassium nitrate goes back to the early Romans and Greeks, who used saltpeter to fertilize their plants. In the third century B.C., the Chinese learned that a mixture of charcoal, sulfur and potassium nitrate could create an explosive powder. Since the Middle Ages, it has played a role in preserving meat and tanning hides, as well ...
How do I make finer potassium nitrate powder? Mill it. Use a ball mill if you have one, and if you're planning to make gunpowder, you should have one. Otherwise you can mill small amounts (a few ounces) of potassium nitrate in a blade-type coffee grinder. If you are, in fact, making gunpowder, and you have a ball mill, you don't need to ...
A ball mill is a rotating drum with dozens of lead balls inside. The 3 chemicals are loaded into the ball mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 and 24 hours. As the ball mill rotates, the lead balls will crush the chemicals together, forcing some of the potassium nitrate into the pores of the ...
The nitrate and charcoal one likely is at least. This general method you mention, with milling two separate mixtures can be done …
Typically, a small coffee mill can efficiently grind about 3 ounces of the potassium nitrate at a time, and 1.2 ounces of the sulfur at a time. It only takes 10-20 seconds for each batch. So to make a 24-ounce batch, you should mill six 3-ounce batches of the potassium nitrate and two 1.2-ounce batches of sulfur.
sucrose and potassium nitrate. The research goal lies on the grinding time, aiming a homogeneous and efficient ... A ball mill was designed and built to assist the research. The mill products go through tests that verify the grains size and, then, are mixed together. Samples are tested in calorimeters and the residues are collected for analysis
In making black powder, I've found that a material charge of 15 ounces of potassium nitrate, 3 ounces of airfloat charcoal, and 2 ounces of sulfur produces the most efficient quantity of BP mill dust.
Prilled nitrate is too coarse to use as-is in making black powder and other fireworks, but once you grind it up to about 200 mesh, it's perfect. Keep in mind that potassium nitrate, like most oxidizers …
