This document is applicable to the determination of the fluorine content in neodymium-iron-boron waste materials. The measurement range (mass fraction) is 0.010% to 1.00%.
This document is applicable to the determination of aluminum, chromium, nickel, and zinc content in rare earth smelting recycling materials from electrolytic and thermal reduction processes. The measurement range for aluminum is 0.020% to 1.50%; and for chromium, nickel, and zinc, it is 0.0050% to 0.10%.
This document contains two methods: X-ray fluorescence spectrometry (Method 1) and inductively coupled plasma emission spectrometry (Method 2). Method 1 is suitable for determining the distribution of 15 rare earth element oxides in praseodymium-neodymium alloy smelting recovery materials, lanthanum-cerium alloy smelting recovery materials, lanthanum reduction recovery materials, and rare earth-iron alloy smelting recovery materials (dysprosium iron, holmium iron, gadolinium iron). Method 2 is suitable for determining the distribution of 15 rare earth element oxides in praseodymium-neodymium alloy smelting recovery materials, lanthanum-cerium alloy smelting recovery materials, lanthanum reduction recovery materials, calcium reduction recovery materials, and rare earth-iron alloy smelting recovery materials (dysprosium iron, holmium iron, gadolinium iron). When the analysis ranges of the two methods overlap, Method 2 shall be used as the arbitration method.
This document is applicable to the determination of the total rare earth content in recycled materials from rare earth pyrometallurgical recovery processes, including electrolytic and thermal reduction processes. This document contains two methods: oxalate weight method (Method 1) and inductively coupled plasma emission spectrometry (Method 2). The determination range (mass fraction) of Method 1 is 5.00% to 90.00%, and the determination range (mass fraction) of Method 2 is 0.50% to 10.00%. When the determination ranges of the two methods overlap, Method 1 shall be used as the arbitration method.
