Dear student,

Aluminium powder is a highly flammable powder created by grinding aluminum into fine grains of material. In times past, this flammable metal powder was used in photography to create bright flashes during a photographic session. Today, aluminum powder is one of the tools utilized in various applications of pyrotechnics including the creation of fireworks displays.

Because of the combustible nature of powder aluminum products, there are a number of restrictions on its sale. In some countries, aluminum powder is only available for purchase to businesses. Even in nations where aluminum powder can still be purchased by individuals, it is not unusual for producers to only sell the powder to suppliers who then sell small lots of the powder to residential customers.

Aluminium powder is one of the most often used fuels in pyrotechnics. A wide range of effects are possible with different types of powder, with differences in particle size, shape and impurities. The finest powders (e.g., German Dark and XD-30) can be 'airfloat', and are commonly used in flash compostions. Fine aluminium is also used in small percentages in some hobby-rocket fuels. Courser powders are generally used for sparkling effects. With these larger particle types, many effects--such as flitter, glitter, firefly and snowball--can be achieved.
