ABSTRACT:
Processes are provided for consolidating diamond particles into a mechanically stable diamond mass, called a diamond ceramic. A compacted aggregation of diamond particles is subjected to low pressure PECVD conditions in the presence of atomic hydrogen, with or without a carbon source gas, whereby a mechanically stable diamond ceramic is formed substantially devoid of interstitial spaces.
