Methods of improving sintering of PCD using graphene |
| 摘要 |
A method of making diamond including mixing graphene with diamond seed to form a powder mixture, and then sintering the powder mixture, in the absence of a transition metal catalyst, at high pressure and high temperature; and a method of making a polycrystalline diamond compact including mixing graphene in diamond powder to form a powder mixture with less than about 50% graphene by weight, and then sintering the powder mixture, in the absence of a transition metal catalyst, at high pressure and high temperature. |
