| Abstract: | FeNi30 catalyst powders were prepared by high-pressure water atomization under different process conditions.The qualitative and quantitative analyses were processed by X-ray powder diffraction and rietveld whole pattern fitting method.The oxygen content of catalyst powder were calculated based on the oxide content and the calculated results,compared with that of the oxygen analyzer.The results show that oxide mainly exists in the form of Fe3O4 and FeO in water atomized FeNi30 catalyst alloy powder,the total oxygen content calculated from oxide content by rietveld whole pattern fitting is in good agreement with the test results by oxygen analyzer,the relative error is under 300×10-6,so the rietveld whole pattern fitting method can be used to rapid determination of effective composition and oxygen content in FeNi30 catalyst alloy powder. |
