Study on the Determination of Molybdenum and Other Elements in Ferromolybdenum Alloy by EDX
Some kinds of the high impurity ferromolybdenum alloy occurred in the ferroalloy market recently. The analysis result of the element Mo in high impurity ferromolybdenum alloy is not accurate using the routine chemical method, because of the co-precipitation of the impurity elements, compared with the final Mo content of poured steel ingots. The energy dispersive X-ray spectroscopy(EDX) was applied to the analysis of ferromolybdenum alloy. The results show that EDX is an appropriate way to the determination of element Mo and Si in ferromolybdenum alloy, but can not be used to analyze element P,S and Cu. As the morphology of the sample has a strong influence on the analysis results, scanning electron microscope(SEM) was used to observe the morphology of the sample. The detection precision of the element shall be raised, when the powder sample of the ferromolybdenum alloy are pressed into thinner disc sample using hydraulic universal testing machine.
