| 发明名称 | Methods of fabricating polycrystalline diamond, and cutting elements and earth-boring tools comprising polycrystalline diamond | ||
| 摘要 | Methods of fabricating polycrystalline diamond include encapsulating diamond particles and a hydrocarbon substance in a canister, and subjecting the encapsulated diamond particles and hydrocarbon substance to a pressure of at least 5.0 GPa and a temperature of at least 1400° C. to form inter-granular bonds between the diamond particles. Cutting elements for use in an earth-boring tool includes a polycrystalline diamond material formed by such processes. Earth-boring tools include such cutting elements. | ||

| 主权项 | 1. A method of fabricating polycrystalline diamond, comprising: encapsulating diamond particles and a hydrocarbon substance in a canister at a temperature below room temperature; and subjecting the encapsulated diamond particles and the hydrocarbon substance to a pressure of at least 5.0 GPa and a temperature of at least 1400° C. to form inter-granular bonds between the diamond particles. | ||
