    Abstract
  • FeMn powder catalyst was employed to synthesize diamond in China-type cubic high-pressure apparatus. Fine single crystal diamond was successfully obtained in the graphite-FeMn system at 5.7 GPa and 1 550 ℃. The optical imaging microscopy observations show that all the synthesized diamond is in light yellow octahedral crystals with grain size of 0.3-0.5 mm. Moreover, there is plenty of white substance in the crystals. The surface morphology of crystals is checked by SEM, and craters can be found in the crystal surface. Mossbauer spectrum is used to detect the impurity in the diamonds. FeMn alloy and independent state Fe are the two states in catalysts, and inclusions in diamond mainly contained Fe and Fe3C. Fe and Mn were detected in the sample using X-ray fluorescent spectrum.
