1 Scope
This document describes the use of wavelength dispersive X-ray fluorescence spectrometry (fused-cast glass sheet method) to determine silica, aluminum oxide,
The content of calcium oxide, magnesium oxide, manganese oxide, vanadium pentoxide, titanium dioxide, chromium trioxide, phosphorus and total iron.
This document is applicable to the determination of multiple elements in vanadium slag. The measurement range of each element (mostly calculated as oxide) is shown in Table 1.
Table 1 Measuring range
Element
Measuring range (mass score)
Silica (SiO2) 5.0~25.0
Aluminum oxide (Al2O3) 1.0~10.0
Calcium oxide (CaO) 1.0~10.0
Magnesium oxide (MgO) 0.50~10.0
Manganese oxide (MnO) 1.0~8.0
Vanadium pentoxide (V2O5) 2.0~30.0
Titanium dioxide (TiO2) 3.0~20.0
Chromium trioxide (Cr2O3) 0.50~10.0
Phosphorus (P) 0.010~0.60
Total Iron (TFe) 20.0~45.0
