Preparation of Iron Nanoparticles by Selective Leaching Method [PDF]
Acta Physica Polonica A, 2015 Iron nanoparticles were prepared by selective leaching method. Initially the rapidly solidified AlFe11 alloy was prepared and consequently the aluminium matrix was dissolved from this alloy in 20% NaOH solution. This process was carried out at 0 and 80°C.
