| Abstract: | In this paper, a new technique of preparing composite pressure transmitting and sealing medium is put forward for diamond synthesis . The outer material is heat treated pyrophyllite and the center material is dolomite in a tube shape. The results from diamond synthesis experiment proved that, the synthesis pressure of the new technique decreased by 2-3 MPa; the synthesis electric current decreased by 100-200A;the unit yield increased by 5 ct; the grit site is relatively uniform, the ratio of 50/60 mesh and grosser reached to 85% ,and the crystal shape is fine. |
| Keywords: | pyrophyllite dolomite pressure and hermetical medium |
