摘要：
Polycrystalline diamond was investigated under high pressure and high temperature of 5.0 GPa and 1100-1500 degrees C in the presence of tungsten. In situ resistance measurements indicated that reactions between diamond and tungsten happened at about 960 degrees C. Phase analysis demonstrated that WC increased and meta-stability of W2C decreased clearly at the higher temperature. It is clear from the characterization of the sintered body that the electrical resistance decreased and the density of specimens increased as the sintering temperature rose. The specimen sintered at 1500 degrees C has a homogeneous microstructure and good conductivity.
