摘要：

The influence of the 'graphitation degree' on the formation of diamond in an anvil type high pressure was studied using different types of graphites. The 'graphitation degree' was measured by a new parameter PHP, related to the percentage of hexagonal perfection. Results have shown that in samples, which presented PHP 'graphitation degree' below 50% no diamond was formed. This suggested that a minimum 'graphitation degree' should be attained in order to have a successful synthesis for diamond production. (C) 2003 Elsevier B.V. All rights reserved.
