Making black powder - PyroCreations

There are two methods to make BP: The ball mill method and the precipitation (or 'CIA') method. You'll need a ball mill in any case. While both methods work, they each have their own advantages and disadvantages. The main disadvantage of the ball mill method is that it is essential that you have a safe place to let your mill do it's work.

Ball Milling Theory Introduction: Figure 1: Ball milling terminology. I was first given the formula for gunpowder by my Uncle at age 14, after he had observed my apparent obsession with class C fireworks. Being a scientist who had experimented with the ancient recipe himself during his youth, he thought I should try making my own fireworks.

Polymer "Tape"‐Assisted Ball‐Milling Method Fabrication ...

However, these methods suffer from the drawbacks of low yield, high cost, or precarious state, which limit the large-scale applications. Inspired by the famous Scotch tape method, we develop a ball-milling with polymer "tape" method, fabricating few-atomic-layered material, showing the high-yield, low-cost, and much stability.

In this study, we developed the first ball-milling method and solvent-free routes for preparing g-C 3 N 4 wrapped α-Fe 2 O 3. The intimate alignment between Fe 2 O 3 and C 3 N 4 results in more efficient charge separation. The Fenton-like activity of 6%α-Fe 2 O 3 @g-C 3 N 4 was almost 3.4 times that of α-Fe 2 O 3 17 times that of g-C 3 N 4 ...

Ball Milling - an overview | ScienceDirect Topics

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
