GB/T 18882.1-2023 Chemical analysis methods of mixed rare earth oxide of ion-absorption rare earth ore—Part 1:Determination of fifteen rare earth oxides composition
Abstract
This document describes the method for determining the distribution of oxides of fifteen rare earth elements in ionic rare earth ores, mixed rare earth oxides, carbonates, oxalates, and rare earth chloride solutions.
This document is applicable to the determination of the distribution of oxides of fifteen rare earth elements in ionic rare earth ores, mixed rare earth oxides, carbonates, oxalates, and rare earth chloride solutions. It includes two methods: Method 1: X-ray fluorescence spectrometry, with the measurement range shown in Table 1. Method 2: Inductively coupled plasma emission spectrometry, with the measurement range shown in Table 2.
