The amount of oxidizer and binder were fixed at 50 wt% and 5 wt%, respectively. Altering the magnesium/hexamine ratio had only little influence on the resulting color: Whereas formulation 1 was dominated by bright white light attributed to the highest magnesium percentage, all other formulations within this row showed a red-violet color with only little blue light emission in the outer flame

Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.

Pyrotechnics

A method of manufacture of pyrotechnics was developed using high-rate evaporation of magnesium onto a PTFE web [122,123].The magnesium was the fuel and the fluorine in the PTFE was the oxidizer. Given ignition, the PTFE would melt releasing the fluorine, and this would react with the magnesium releasing heat that would help sustain the process [124,125].
