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 ~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.
On forme des matières de type diamant en prenant en sandwich un matériau contenant du carbone (106) dans un espace entre deux électrodes (102 et 104). On applique un courant à haute intensité au moyen d'une alimentation (110) entre les deux plaques d'électrodes de manière à provoquer un chauffage rapide du matériau contenant du carbone. Le courant est suffisant pour augmenter la température du matériau contenant du carbone à plus de 1000 ~C. Le matériau contenant du carbone est soumis à un refroidissement rapide par un dissipateur de chaleur (130). Ce dissipateur de chaleur peut être en contact avec l'une des électrodes. Ce procédé est repété jusqu'à la formation du diamant. Un gaz inerte ou protecteur (140 et 142) est étalement utilisé au cours de ce procédé.
