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.
Claims7
A process for consolidating diamond particles into a mechanically stable diamond mass comprising the step of contacting a compacted aggregation of diamond particles with atomic hydrogen, a gaseous carbon source and an agent which improves carbon atom mobility upon surfaces of said particles, under conditions whereby diamond is epitaxially deposited onto said diamond particles, causing said particles to consolidate into a mechanically stable diamond mass substantially devoid of interstitial spaces.
A process for consolidating diamond particles into a mechanically stable diamond mass comprising the step of contacting a compacted aggregation of diamond particles with atomic hydrogen under conditions whereby said particles gasify and redeposit as a mechanically stable diamond mass substantially devoid of interstitial spaces.
