XRF melting glass method ferromanganese, manganese silicon alloy and metal manganese

Silicon and silicon manganese alloy steel smelting is the main additive and deoxidizer, accurate determination of which each element is very necessary. As alloy analysis usually adopt chemical analysis method for determination of silicon and manganese, main elements by ICP atomic emission spectrometer to determine the various impurity elements, in terms of its method of chemical analysis method takes a long, complicated operation, ICP analysis time is long, and the need for sample decomposition. Through a large number of experimental studies to determine the sample granularity, sample ring material, such as sample preparation methods, determination of conditions using XRF melting method of determination of silicon and silicon manganese alloy, can direct glass fuse piece method, at the same time the main elements and the impurity elements, a total of 16 11 common elements, simplifies the test steps, reduce the labor intensity, satisfactory results are obtained

XRF fuse link analysis, there is a sample direct calcination and melt quality change different error, commonly used dilution ratio unable to correct the error correction, through the fixed quality (volume) in the flux of fused into the series of measured components quality of oxide was prepared (volume) of the same standard glass series, x ray fluorescence intensity and glass plates volume concentration of the measured components Function curve, using the result of the measurement sample quality and the quality of the calibration curve of glass glass than the calibration results of the analysis, namely pure material quality correction instead of dilution ratio correction (Mn0_2, Si0_2, (NH_4) _2HPO_4 and Fe_20_3) as the standard, with the selected type vacuum EDX9000A alloy analyzer working conditions, established the department of manganese alloy analysis with Mn, Si, Fe, P the mass fraction of fluorescence intensity calibration curve, the linear correlation coefficient respectively0.99993, 0.99998, 0.999 96,0.99981. Investigates the accuracy of the calibration curve with standard sample, the results are very satisfactory. The glass fuse piece perfect application in XRF spectrometer sample preparation method.

“Ray fluorescence spectrometer EDX9000B PLUS alloy analyzer determination of silicon and silicon manganese alloy results are as follows
