Abstract
EXAFS measurements have been carried out on mixtures of Sn with Ge and Si, and Pt with SiO2 which have been ball milled for extended periods. In these systems the brittle component (Ge, Si, or SiO2) 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-SiO2 system while no mixing is observed, the Pt is found to be highly dispersed on the surface of SiO2 particles.
