Conversion of graphite to diamond assisted by non-metallic catalysts under high pressure and high temperature: A review

Abstract

Recent results of the investigation of conversion from graphite to diamond by the aid of non-metallic catalysts are reviewed in this article. The current status of experimental advances is presented and typical examples from relevant literature are provided for understanding the mechanism of the graphite-diamond conversion by aid of these non-metallic catalysts. Finally, a few questions are raised which may be useful for the continued development of this field.

Key Words:

• Graphite-diamond transition
• non-metallic catalyst
• high pressure
• high temperature
