Aluminium powder is powdered aluminium. This was originally produced by mechanical means using a stamp mill to create flakes. Subsequently, a process of spraying molten aluminium to create a powder of droplets was developed by E. J. Hall in the 1920s. The resulting powder might then be processed further in a ball mill to flatten it into flakes for use as a coating or pigment. Aluminium powder is non toxic and is not harmful unless injected directly in a major blood vessel such as the aorta. Aluminium powder, if breathed in, it is not particularly harmfull and will only cause minor irritation.[1]
Usage
- cosmetic colorent[2]
- pyrotechnic
- in paints as metalic silver pigment
- Fingerprint Powder
- Rocket and missile Fuel
- thermite
Depending on the usage, the powder is either coated or uncoated.
