The aluminum powders PA-0, PA-1, PA-2, PA-3, PA-4 represent the product of silver-gray color with metal gloss which is not containing the foreign particulates and bound together lumps which are not scattered from a light touch.

Powders receive spraying of the melted primary aluminum or its waste and the subsequent rassev on fraction. Aluminum PAS powder is made of primary aluminum.

Use of aluminum powders in different industries.
1. Ore mining industry.
Aluminum powders as high-energy additives are a part of many industrial explosive substances (ES) which are applied in the mineral industry - ammonals, rocky ammonites, detonit, alumotrinitrotoluene. At the same time warmth of explosive transformation of VV and indicators of their working capacity significantly increases.
2. Ferrous metallurgy.
In ferrous metallurgy aluminum powders (granules) are applied as a reducer. The additive of 0,1-1,5% of an aluminum krupka to smelted iron completely exempts it from protoxide and by that provides dense casting without sinks. Aluminum powders are used for heating of a shrink head of an ingot at ferrous metal casting. Around a pouring opening and profit fill mix from oxides and aluminum powders which "is lit" from fusion and, burning down, long time supports cast metal in a liquid state. It allows during the hardening of casting and reduction at the same time of the volume of metal to add a form and to avoid thereby formation of pipes in castings. By production of ferroalloys aluminothermic recovery of oxides of refractory metals is widely used. Thus receive ferro-molybdenum, ferronioby, ferro-tungsten, etc., at the same time usually use powders fineness from 5 to 300 microns. World distribution was gained by the thermite mixes Fe2O3 - Al. Stoichiometrical mix of 75% Fe2O3 + 25% of Al gives firing temperature about 2500 °C.
3. Chemical industry.
In chemical industry aluminum powders and granules successfully apply to recovery virgin soils as they quickly react in water acidic or alkaline environments with a hydrogen release which at the time of education is one of the strongest reducers: 1 kg of aluminum powders gives 1240 l of hydrogen. Aluminum powders find broad application when receiving aluminum alkyls, at polymerization of ethyls, productions of an anti-detonator of tetraethyllead, etc.
4. Receiving aluminum coverings on metals.
Aluminum powders are applied to drawing coverings, generally on steel products. The greatest application was received by spray coating, plasma spraying and powder metallurgy (knurl of powders on a surface of a steel sheet with the subsequent heat treatment).
