摘要

Boron-doped diamond has been synthesized from graphite mixed with different ratio of B 4 C at high pressure high temperature (HPHT) using laser heated diamond anvil cell.The starting composition was transformed to diamond compound at pressure ~9 GPa,2300-2400 K as indicated by the in-situ X-ray diffraction pattern with synchrotron radiation source.Raman spectrum of the recovered specimen from HPHT state confirmed that boron has been doped into diamond lattice.
