During the ball milling process the particle surfaces are mechanically and thermally activated and oxidation reactions could occur at the surface. Those oxidation products could be identified in the Mo 3d and S 2p XPS detail spectra of the ball milled samples (sample 2) namely MoO 2 MoO 3 MoS 2 O 0.5 MoS 2-x O x FeSO 4 and Fe 2 (SO 4) 3

Magnesium powder in micron scale and various volume fractions of SiC particles with an average diameter of 50 nm were co-milled by a high energy planetary ball mill for up to 25 h to produce Mg-SiC nanocomposite powders. The milled Mg-SiC nanocomposite powders were characterized by scanning electron microscopy (SEM) and laser particle size analysis (PSA) to study morphological evolutions.

Abstract. Metal-oxide composites were synthesized by high-energy ball milling of metallic iron (α-Fe) and alumina (α-Al 2 O 3) powders varying the starting relative concentration and the milling time.The samples were characterized by scanning electron microscopy x-ray diffraction and Möss spectroscopy.

Composites processing and characterization. All ball-milled samples contained sub-micron particles and the number of sub-micron particles increased with ball milling time. Furthermore although most of the particles had irregular shape the particles milled for a longer period of time were less likely to have sharp corners

Ball milling was performed with a Spex 8000 mill with hardened steel vial and balls. The temperature obtained during cryo-milling was estimated to be 85 K by Klassen et al. . Thereafter we refer to this temperature as LN2. The powders were first pre-alloyed by milling at room temperature for 24 h and then milled for 5 h at low temperature.

Ball-milled biochars (BM-biochars) were produced through ball milling of pristine biochars derived from different biomass at three pyrolysis temperatures (300 450 and 600 °C). The results of scanning electron microscopic (SEM) surface area hydrodynamic diameter test and Fourier transform infrared spectroscopy (FTIR) revealed that BM-biochars had smaller particle size (140–250 nm

Biocarbon obtained by the pyrolysis of miscanthus was subjected to ball milling from 2 to 24 h. Particle analysis was performed by combining scanning electron microscope imaging and image-based particle counting. The milled biocarbon had a highly heterogeneous shape and size distribution making image-based analysis the most suitable method.

A homemade ball mill was constructed and optimized in order to prepare nano crystallite size of tungsten heavy alloys with composition of 90W-7Ni-3Fe and 90W-7Ni-3Co in wt . The samples were mechanically alloyed under high purity of argon atmosphere and were sintered under high vacuumat 1200°C 1300°C and 1400°C.

Abstract. Ball milling is an effective way of producing defective and nanostructured graphite. In this work the hydrogen storage properties of graphite ball-milled in a tungsten carbide milling pot under 3 bar hydrogen for various times (0–40 h) were investigated by TGA-Mass Spectrometry XRD SEM and laser diffraction particle size analysis.

High-energy ball milling of monoclinic ZrO 2 -30 mol anatase TiO 2 mixture at different durations results in the formation of m-ZrO 2 -a-TiO 2 solid solution from which the nucleation of nanocrystalline cubic (c) ZrO 2 polymorphic phase sets in. Post-annealing of 12 h ball-milled sample at different elevated temperatures for 1 h results in almost complete formation of c-ZrO 2 phase.
