Description

The thermal changes taking place at the sites of Fe-Co metal inclusions in synthetic diamond grains have been investigated using Moessbauer spectroscopy on as-grown samples and samples annealed at 970-1370 K. The spectra show the presence of Fe-Co and (Fe-Co)-C complexes. The temperature-dependent results suggest that the latter are due to reactions at the metal inclusion-diamond interface, and may be a signature of the processes leading to strength loss in the grains.
