Abstract

Cette invention concerne un procédé de production de diamants artificiels, lequel se rapporte aux techniques de production de matériaux d'une grande dureté et, plus précisément, à la synthèse de diamants que l'on utilise principalement dans la fabrication d'instruments diamantés. Ce procédé de production de diamants artificiels consiste à exercer une action sur du graphite contenant du fullerène et sur un catalyseur, ceci en appliquant une pression et une température dans la plage de stabilité du diamant, puis en maintenant le mélange à la température et à la pression de synthèse. Ce procédé se caractérise en ce que l'on introduit du fullerène selon une quantité représentant de 10-2 à 6 x 10-1 % en poids de la masse de graphite, et en ce que ledit fullerène est réparti dans la masse de graphite. Le fullerène peut être introduit sous forme de suies contenant du fullerène ou sous forme de concentré de fullerènes. Ce procédé permet d'accroître la production de diamants artificiels à des pressions ne dépassant pas 5,5 GPa.
