Industrial single crystal diamonds were synthesized from FeNi powder catalyst in a China-type cubic anvil high-pressure apparatus.In a series of experiments,we successfully synthesized high-quality cubic,cubic-octahedral and octahedral diamond single crystals.From the morphology of the synthesized diamond,we found the{1 1 1}plane obeyed the two-dimensional layer growth mechanism. The M?ssbauer spectra indicate that the main components of the impurity are FeNi alloy in the diamond.
