FORMATION OF DIAMOND MATERIALS BY RAPID-HEATING AND RAPID-QUENCHING OF CARBON-CONTAINING MATERIALS.

摘要

Diamond materials are formed by sandwiching a carbon-containing material (106) in a gap between two electrodes (102 and 104). A high amperage current is applied by power supply (110) between the two electrode plates so as to cause rapid heating of the carbon-containing material. The current is sufficient to elevate the temperature of the carbon-containing material over 1000 degree C. The carbon-containing material is then rapidly quenched by a heatsink (130). The heatsink can be in contact with one of the electrodes. This process is repeated until the diamond has formed. Also, a shielding or inert gas (140 and 142) is used during the process.
