Fe nanopowdersball milling

Hematite (α- Fe 2 O 3 ) and magnetite (Fe 3 O 4 ) powders, milled for various times up to 10 hours by a high energy ball milling technique, were structurally and magnetically characterized by X-ray diffraction and magnetic measurements in magnetic field up to 10 T in the 2 K-300 K temperature range. From X-ray diffraction line analyses, it is found that when the milling time is increased, the ...

Nanocrystalline Ni 036 Zn 064 Fe 2 O 4 was synthesized by milling a powder mixture of Zn NiO and Fe 2 O 3 in a highenergy ball mill for 30 h under three different atmospheres of air argon and oxygen After sintering the 30 h milled samples at 500176C the XRD patterns suggested the formation of a single phase of NiZn ferrite.

Oct 12, 2015· In this research, nearly spherical CuO nanopowders (NPs) were synthesized in a high-energy ball-milling method at room temperature for different milling times (20 and 40 h) at dry medium. The structure, particle size, purity and morphology of the resulting CuO NPs were characterized by X-ray diffraction, inductively coupled plasma and scanning electron microscopy (SEM) techniques.

Nanophase elemental Fe powders prepared by mechanical milling were sinter forged to full density with an average grain size in the nanophase range (below 100 nm). If Cu additions are introduced during milling to form supersaturated solid solutions (Fe{sub 85}Cu{sub 15} and Fe{sub 60}Cu{sub 40}), grain sizes can be easily controlled to below 50 nm after consolidation.
