  • Diamond synthesis process
    Patent number: 4481180
    Abstract: The present invention relates to a diamond synthesis process.A stack of graphite and alloy pellets of at least one metal of group VIII or VII of the periodic system with an element having the same crystallographic structure as the diamond are placed in an enclosure. The pressure and temperature are raised so that the alloy starts to liquefy. Part of the element remains in the state of solid particles used in the nucleation by epitaxy of the diamond crystals. The carbon migrates through the liquid alloy from the pellets to the solid particles.
