For all nanocrystalline materials prepared by high-energy ball milling synthesis route surface and interface contamination is a major concernIn particular mechanical attributed contamination by the milling tools fe or wc as well as ambient gas trace impurities such as o 2 n 2 in rare gases can be problems for high-energy ball milling.
Further milling resulted in a high level of wc contamination which apparently was due to work hardening and the grain refinement of wA sintered density as high as 974 was achieved by sintering cold isostatically pressed nanocrystalline 8 nm w powder at 1790 c for 900 min.
Graphene oxides go with different degrees of oxidation have been prepared by an in-house designed horizontal high energy planetary ball milling process.

Jan 31 2011 fully stabilized cubic zirconia doped with iron oxide has been synthesized by high-energy ball milling from powder mixtures of monoclinic zirconia and hematiteIt is found that the iron ions dissolved in cubic zro 2 are in substitutional positions with a maximum solubility of approximately 18.
Oct 12 2007 the powders were ground in a milling vial with balls made of 440c hardened steel by using a spex 8000m high-energy ball milling machineThe milling process and handling of the starting materials and the milled products were carried out in an argon gas environment inside a glove box to protect the particles from oxidation.

The high energy ball milling technique permits production of composite powders suitable for application in thermal spray processesDifferent milling systems are compared concerning their potential for production of composite powder feedstock for spraying processes.
This is a first systematic report on the synthesis of completely nanocrystalline metals by high-energy deformation processesPure metals with body-centered cubic bcc and hexagonal close-packed hcp structures are subjected to ball milling resulting in a decrease of the average grain size to ≈9 nm for metals with bcc and to ≈13 nm for metals with hcp crystal structures.
