Preparation of nanocrystalline materials by high-energy milling

Various types of nanocrystalline materials have been prepared using high-energy milling. Bismuth–ceramic (Bi/MgO, Bi/Al 2O 3, Bi/SiO 2) and copper–iron sulphide (Cu/FeS) composites as well as lead sulphide (PbS) nanocrystalline particles have been synthesized with this technique. X-ray powder diffra...

Description
Summary:Various types of nanocrystalline materials have been prepared using high-energy milling. Bismuth–ceramic (Bi/MgO, Bi/Al 2O 3, Bi/SiO 2) and copper–iron sulphide (Cu/FeS) composites as well as lead sulphide (PbS) nanocrystalline particles have been synthesized with this technique. X-ray powder diffraction was used to characterize the composition and particle size of as-prepared nanopowders. PbS particles as nanophase may be prepared in the laboratory planetary mill as well as in an industrial vibratory mill. High-energy milling thus has considerable possibility for easily scaling up the production of advanced materials under ambient conditions in reasonable time without the use of any solvent.
