· Empirical coefficient method EC-X-ray fluorescence spectrometer EDX9000B to determine 10 components in magnesium refractory materials

In order to adapt to the measurement of all kinds of magnesia refractory material, experiment with samples and mixed solvent (Li2B407 – LiBO2 – LiBr) dilution ratio of 1:10, 1 050 ℃ melting 20 Min preparation of glass, the application of X-ray fluorescence spectrometer (XRF) EDX9000B determination of MgO style in magnesia refractory, CaO, SiO2, A1203, Fe203 and MnO, P205, TIO2, Cr203, K20 of 10 kinds of components, with the spectrum pure substances, standard samples, samples of pure substance and the standard solution synthesis Joint production, chemical constant value sample calibration curve, criterion by the empirical coefficient method for matrix of the comparison between the calculated value to select the correction of matrix effect correction of components involved in, each group of curve fitting accuracy, effectively overcome the determination of components in magnesia refractory matrix effect to precision test of samples, the influence of the relative standard deviation (RSD, n = 7 ) is between 0.053% ~ 3.1%. Accuracy of standard sample and unknown sample inspection, the measured value and the value or wet – cause
