【Abstract】 A study was undertaken to decrease the sintering temperature and to increase the thermal stability of diamond by adding rare earth elements. The critical factor in the activated sintering is the content of rare earth element. The results show that adding 0.3% rare earth to the powders makes the composites obtain the properties needed.更多还原
