This document was first published in.2010, and this is the first revision.IntroductionThe rare earth iron alloy referred to in this document refers to the master alloy composed of iron and one or more rare earth elements, which is generally adopted by molten salt electrolysis or fusion It is mainly used as an additive for magnetic materials such as NdFeB permanent magnet materials, magnetostrictive materials, optical and magnetic recording materials, or as a deoxidizer, Additives, etc. are used in iron and steel smelting. Chemical composition is an important assessment index of rare earth ferroalloys. This series of standards GB/T 26416 "Rare earth iron Alloy Chemical Analysis Method" integrates the industry standard XB/T 616-2012 "Chemical Analysis Method of Gadolinium Iron Alloy", XB/T 621-2016 "Holmium Ferroalloy Chemical Analysis Method", XB/T 623-2018 "Cerium-Fe Alloy Chemical Analysis Method", XB/T 624-2018 "Chemical Analysis Method of Yttrium-Fe Alloy "Analysis Method", to establish the current large-scale production of rare earth ferroalloys (including ferro-lanthanum, ferro-cerium, ferro-lanthanum-cerium, ferro-Nd, ferro-dysprosium, ferro-gadolinium, ferro-gadolinium, holmium iron and yttrium iron, etc.) in the production and application of the chemical analysis method standards for indicators that need to be assessed, including the total amount of rare earth, rare earth impurity content, non-rare Detection of soil impurity content, etc. According to the different detection objects and detection methods, as well as the differences in the matrix, GB/T 26416 is proposed to be composed of 9 parts Composition. --- Part 1.Determination of the total amount of rare earth; --- Part 2.Determination of rare earth impurity content Inductively coupled plasma emission spectrometry; --- Part 3.Determination of calcium, magnesium, aluminum, nickel, manganese content Inductively coupled plasma emission spectrometry; --- Part 4.Determination of iron content Potassium dichromate titration method; --- Part 5.Determination of oxygen content pulse-infrared absorption method; --- Part 6.Determination of molybdenum, tungsten and titanium content Inductively coupled plasma emission spectrometry; --- Part 7.Determination of carbon and sulfur content High-frequency-infrared absorption method; --- Part 8.Photometric method for the determination of the amount of silicon; --- Part 9.Determination of phosphorus content Bismuth phosphomolybdenum blue spectrophotometry. The above-mentioned standards have clarified the scope of application, standardized reagents, materials, test equipment and procedures, and have been repeatedly tested by many laboratories. The precision data given by the repeated tests and verifications has enhanced the consistency and comparability of data between different laboratories, and provided a basis for the quality assurance of rare earth ferroalloys. Establish a rigorous and standardized standardization work foundation.
