摘要：

Oriented diamond crystals have been formed on polycrystalline platinum by a multi-step low-pressure solid-state carbon source processing route employing Pt as the metallic solvent. The processing routine included the implementation of a high-temperature metal hydrogenation step at 900 degrees C, followed by an increasing metal carbonization step at temperatures of 1100, 1200, 1300 and 1400 degrees C. For the carbonization step at temperatures of 1300 degrees C and greater, prior to exsolution and diamond formation, regions with oriented diamond particles were observed. However, when performing this procedure at less than 1300 degrees C only randomly oriented particles were observed. (C) 1997 Elsevier Science S.A.
