EXAFS Study of Metal-Coated Particles Produced by Ball Milling
EXAFS measurements have been carried out on mixtures of Sn with Ge and Si, and Pt with SiO 2 which have been ball milled for extended periods. In these systems the brittle component (Ge, Si, or SiO 2 ) is ground to nanocrystalline dimensions while the ductile metal is found to coat the outer surface...

Summary: | EXAFS measurements have been carried out on mixtures of Sn with Ge and Si, and Pt with SiO
2
which have been ball milled for extended periods. In these systems the brittle component (Ge, Si, or SiO
2
) is ground to nanocrystalline dimensions while the ductile metal is found to coat the outer surface of the particles. Analysis shows that in the Sn-Ge and Sn-Si systems, mixing at the interface is found to form apparently cubic SnGe and SnSi alloys respectively. In the Pt-SiO
2
system while no mixing is observed, the Pt is found to be highly dispersed on the surface of SiO
2
particles. |
