Abstract

The graphite-encapsulated iron nanocrystals can be made by electron beam irradiation of iron particles on an amorphous carbon support in situ. The microstructure and defects of a new calcium iron (II) titanate compound was studied to demonstrate the technique. The mechanism for the encapsulation involves electron excitation processes. The demonstration of the electron beam introduced nanoscale encapsulation of iron crystallites within a protective graphite cage and it may be extended to many other materials to permit the utilization of a wide range of environmental sensitive materials for applications not previously possible.
