Test methods for physical properties of rare earth metals and their compounds - Part 1: Determination of particle size distribution of rare earth compounds - Laser diffraction method

This document describes a method for determining the particle size distribution of rare earth compounds using laser diffraction.

This document applies to rare earth oxides, rare earth composite oxides, rare earth carbonates, and rare earths with a particle size distribution ranging from 0.1 μm to 500 μm.

Particle size distribution determination of polishing powder and rare earth sulfide compounds.
