METHOD FOR PRODUCING SYNTHETIC DIAMONDS

摘要

A method of producing diamonds comprises the steps of providing a nano-structured carbonaceous material, and thermally treating the nano-structured carbonaceous material in an oxygen-containing environment so as to produce diamonds. The nano-structured carbonaceous material may be materials such as carbon nano-particles, carbon nano-tubes and carbon nano-scrolls. It is preferred that the nano-structured carbonaceous material is created by electrochemical erosion of graphite. Thermal treatment to form the diamonds may occur in a temperature window within which the nano-structured carbonaceous material oxidises but diamond crystals are relatively more stable.
