Study of the different drying conditions on MnO2 and Fe2O3 Nanoparticles based on the nano Alumina prepared by wet impregnation Method

In this article the nanoparticles of iron- manganese based on nano Alumina oxide, with method of wet impregnation with experimental substances; Fe (NO3) 3 . 9H2O and Mn (NO3)2 . 6H2O in different times and temperatures have been synthesized .Done examine on effectiveness of drying conditions at the different temperatures and times on over particles size and morphology performed. Structural characteristics by using identification method XRD done, the peaks of related indicator Fe2O3 and Al2O3 (rumbuhedral) MnO2 ( cubic) observed.Morphology and the size of crystals with the SEM device determine and taken images from particles of the iron- manganese oxide particles showed that obtained crystals the dimensions between 20 nm up to 60 nm have and having the rumbuhedral structure are. And also to determine the chemical composition of the investigated samples in vitalize conditions of radiation x, the energy dispersive x- ray (EDX) used that obtained results from EDX analysis the presence of the desired elements (O, Fe, Al, Mn) in the sample confirmed.
