Scope

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.
