  • Diamond grains, method for making same and mixture comprising same
    Patent number: 10047455
    Abstract: A method of providing well-shaped diamond grains of at most about 100 microns in size. The method includes providing a synthesis assembly comprising a source of carbon material, a plurality of seed grains on which diamond material can crystallize, and solvent-catalyst material for promoting the crystallization of the diamond grains, and subjecting the synthesis assembly to a condition for growing the diamond grains. The synthesis condition is maintained long enough for at least about half of the carbon material to be converted into the diamond grains.
    Type: Grant
