Состав и структура защитной оксидно-гидроксидной оболочки на частицах нанопорошка алюминия

It was ascertained that the structure of hydroxide phases in composition of surface layer of aluminum nanopowder particles depends on passivation conditions, conditions and duration of storage, size of aluminum nanopowder particles and admixture occurrence. It was shown that thermal treatment of aluminum nanopowders to 550 °С results in formation of oxide y-Al2O3 particles on the surface. The diagram of forming hydrox-oxide layer on aluminum surface was introduced.
