The products related to rare earth elements in our daily life are mostly in powder forms, such as rare earth oxides, rare earth salts, and rare earth hydroxide et al. Particle characterization testing is an experimental work to describe the particle characteristics of powders through specific instruments and methods. In order to study the microscopic properties of powder-form rare earth related products, particle characterization parameters can describe their physical properties in detail. Among various indicators, particle size distribution is the most concerned indicator in all application fields.

Particle size
Particle size is an effective way to describe and characterize the size characteristics (length, width and height) of particles. Each particle has a specific shape and different three-dimensional elongation, however, particles are actually represented by one-dimensional size functions (for example, chord length, particle length, or spherical equivalent diameter).
Particle size distribution
The percentage of particles of different sizes in the total amount of powder reflected by specific instruments and methods. There are two forms of interval distribution and cumulative distribution. Interval distribution is also called differential distribution or frequency distribution, which represents the percentage of particles in a series of particle size intervals. The cumulative distribution is also called integral distribution, which represents the percentage of particles smaller or larger than a certain size.
