Aluminum powder "Indian Black", flake, 5µm

Product information "Aluminum powder "Indian Black", flake, 5µm"

This aluminum powder is made in India. A previously produced aluminum spray grit is ground in ball mills with the help of fatty acids . Here the primary particles undergo a change in size, but more importantly a change in shape. The resulting particles are now platelet-shaped and extremely reactive due to the large surface area.

This powder is one of the dark types and is used almost exclusively for reactive purposes. The use as a pigment is therefore unusual.

Preferred areas of application

  • Aerated concrete
  • Chemical reducing agent / gas generators
  • Pyrotechnics
