Notes:
This paper described the preparation method for composing high-grade syntheticdiamond by water atomizing using FeNi30 powder catalyst.The FeNi30 powder was corroded bythe 100Mpa super high-pressure water atomizing technique and selecting organic RY corrosioninhibitor. Contrast test of the original FeNi30 powder and the treated FeNi30 powder on syntheticdiamonds were conducted under super high-temperature and high-pressure using cubic press. Theresult shows that after the FeNi30 powder was corroded,the FeO phase and Fe3O4 phase could notlonger be found by X-Ray analysis.Furthermore,the oxygen content of the powder increased up to100PPM under the natural condition for one year. After the powder was mixed with graphitepowder, diamond could be made by isostatic pressing method. Its color became darker and its TTIvalue increased slightly. However, its penetrability was still different from the high-grade syntheticdiamond made by gas atomizing FeNi30 powder catalyst
