Foreword

This standard is proposed and managed by the National Certification and Accreditation Administration. This standard was drafted. Qinhuangdao Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China and the Bayuquan Entry and Exit Inspection of the People's Republic of China Quarantine Bureau. The main drafters of this standard. Jiang Haitao, Lin Zhong, Liu Yongming, Jiang Xiaoguang, Li Weigang, Gao Xiangqi. This standard was first published. Determination of chromium, silicon, iron, aluminum, magnesium and calcium in chrome ore Wavelength dispersion X-ray fluorescence spectrometry  range This standard specifies methods for the determination of chromium (1), silicon, iron, aluminum, magnesium and calcium in chromium ore by wavelength dispersive X-ray fluorescence spectrometry. This standard applies to chromium ore as shown in Table 1 in the range of the components to be tested. 1) When the chromium content is used for trade pricing, it is for reference only. Component mass fraction range Cr2O3 32~55 SiO2 2～15 Fe 9～18 Al2O3 9～13 MgO 10～21 CaO 0.1~1.0 The terms in the following documents become the terms of this standard by reference to this standard. All dated references, all subsequent Modifications (not including errata content) or revisions do not apply to this standard, however, research that encourages agreements based on this standard is No, the latest version of these files can be used. For undated references, the latest edition applies to this standard. ISO 6153.1989 chrome ore - take a sample ISO 6154.1989 chrome ore - sample preparation  Principle Using hexametaphosphate and lithium metaborate as mixed flux, lithium bromide as release agent to prepare chrome ore sample, measured by X-ray fluorescence spectrometer The intensity of the X-ray fluorescence spectrum of the characteristic line of the element to be tested is measured, according to the intensity of the X-ray fluorescence spectrum of the element to be tested and the content of the element to be tested The quantitative relationship between them calculates the content of the element to be tested. Unless otherwise stated, only analytically pure reagents and distilled water were used in this standard analytical method. Hey.  Sodium hexametaphosphate [(NaPO3)6]. baked at.200 ° C for 2 h, placed in a desiccator for storage. Hey.偏 Lithium metaborate (LiBO2). a special reagent for fluorescence, which is burned at 550 ° C for 4 h and stored in a desiccator.
