Method for consolidating diamond particles to form high thermal conductivity article

摘要

Method for consolidating diamond material, substantially free of voids, has an average crystallite size greater than about 15 microns, a maximum intensity of the diamond Raman peak in counts/sec divided by the intensity of photoluminescence at 1270 cm-1 greater than about 3, a Raman sp3 full width half maximum less than about 6 cm-1 and a diamond-to-graphite Raman ratio greater than about 25. The diamond material may also comprise carbon atoms with a C13 content less than 0.05 atomic %.
