GB/T 40311-2021Vanadium slag—Determination of multi-element contents—Wavelength dispersive X-ray fluorescence spectrometry(fused cast bead method) (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

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.
