SN/T 2749-2010 《Determination of manganese,silicon,aluminum,calcium,titanium in rare earth ferrosilicon.Wave dispersive X-ray fluorescence spectrometry method》 Related products

This standard specifies a method for the determination of manganese-silicon, aluminum, and calcium-titanium in rare earth ferrosilicon alloys by wavelength dispersion X-ray fluorescence spectrometry, which is suitable for the determination of these elements in rare earth ferrosilicon alloys imported and exported. Using solid sample powder pressing wavelength dispersion X-ray fluorescence spectrometry, the content is calculated according to the quantitative relationship between the X-Rays fluorescence intensity of the element to be tested and the content of the element to be measured. Normative reference documents include Precision of Measuring method, General principles of X-fluorescence spectrometry for analytical methods of metallurgical products, etc. Required reagents include manganese dioxide, titanium dioxide, calcium oxidation, rare earth ferrosilicon standard samples, etc. Instruments include wavelength dispersion X- Fluorescence Spectrophotometer and hydraulic press.
