Effect of Additive La₂O₃ on Synthesizing Diamonds Using Pure FeNi Powder Catalyst

Abstract:

In this paper, industrial diamonds using FeNi powder catalyst with additive La2O3 has been synthesized by HPHT method. Optical microscope, XRD and SEM were utilized for observation and detection. The influences of additive La2O3 on the synthesis have been investigated from several aspects such as the diamond-forming conditions, the composition of synthesized sample and inclusions in diamond, and the morphology character of diamonds etc. The results indicate that There is a new compound LaO, LaFeO3, Fe3C and Fe3O4 in the sample., and related phenomena were given in detail in this paper.
