High-energy mechanical milling of the FeS2 pyrite led to the formation of sub-micron particles with nano-scaled grains. FeS2 nanoparticles were obtained, when NaCl.was used as the dispersion medium. FeS2 pyrite and FeS troilite phases could be formed after high-energy mechanical milling. The formation of FeS2 pyrite required a long milling time. The resultant powders consisted of nano-scaled particles. The use of the solid dispersion medium (NaCl) can promote dispersion of nanoparticles. This work has shown that iron sulfide nanoparticles can be synthesized by mechanochemcial process with a solid dispersion medium. (C) 2004 Elsevier B.V. All rights reserved.
