Abstract
1476313 Growing diamond crystals NATIONAL RESEARCH DEVELOPMENT CORP 29 May 1974 [7 June 1973] 27293/73 Heading B1S [Also in Division Cl] A method of growing a diamond crystal comprises bombarding the diamond with carbon ions of sufficient energy to penetrate the diamond crystal, and cause internal crystal growth, the temperature being such that the diamond crystal structure is maintained during growth. Preferred conditions are carbon ion energies of 1-100 keV and temperatures of at least 600‹C. Impurity ions such as nitrogen ions may be present in the carbon ion beam, to produce e.g. colours
