Aluminum is the third most commonly occurring element in the Earth crust. This metal is very reactive and is characterized by high heat of combustion. Aluminum is widely used in various technical fields such as: space technology, production of common use items, cars, airplanes, high energy materials. Aluminum in the shape of flakes or granulated with different particle size (nanoand micro-) is used in different mixtures. Aluminum powder is used as a component in rocketpropellants, pyrotechnics, primary or secondary explosives. Aluminum as one of the components of solid rocket propellants acts as metallic fuel and particle size of aluminum influences the utility properties of products. Particle size and aluminum content affects the viscosity of rocket propellant mixture, burning time, ignition temperature, ignition delay time and specific impulse. Description of the influence of aluminum external layer modification on properties of aluminum combustion in rocket propellant is presented. Aluminum acts as fuel in pyrotechnic mixtures. Aluminum size can effect parameters such as decomposition temperature and ignition temperature in pyrotechnic mixtures. One type of pyrotechnic mixtures are thermites. Introducing nano-sized aluminum to thermites creates mixtures with new properties called superthermites, nano-thermites or metastable intermolecular composites (MICs). Nano-thermites can be characterized by a different combustion characteristics in comparison with standard thermites. Studies on firecrackers sound volume depending on the used particle size of aluminum were also shown.
