Abstract:
      Abstract: To improve the inspection efficiency of ferroniobium alloy and replace the complicated wet chemical analysis, this paper uses powder pressing to make samples and X-ray fluorescence spectrometry to analyze the five main components of Fe, Nb, Si, Al and P in ferroniobium alloy. Methods selected the fixed value production sample as the internal control standard sample, mainly studied the influence of sample preparation details on the analysis results, and confirmed the appropriate sample size and tablet pressing parameters. The production sample after constant value is used as the calibration standard sample, and the calibration curve is established by curve fitting. Compared with chemical wet method and inductively coupled plasma atomic emission spectrometry, the relative standard deviation of each component is 0.48-1.9%, and the accuracy meets the requirements of national standard.
