Application of laser particle size analyzer in rare earth particles

The size of rare earth particles has many effects on their applications, as follows:

Magnetic material applications

Advantages of small particles: When preparing rare earth permanent magnet materials, smaller rare earth particles help to increase the coercive force of the material. For example, in nanocomposite permanent magnet materials, when the particle size is reduced to a single domain size, the coercive force reaches its peak, which can significantly improve the performance of the magnet.         

Catalyst applications

Advantages of small particles: When the rare earth particles are small, the specific surface area increases, the number of surface atoms increases, and the active sites increase, which can more effectively contact the reactants, thus improving the activity and selectivity of the catalyst. For example, in three-way catalysts used for automobile exhaust purification, small particles of rare earth elements can better disperse precious metals, improve the catalyst's anti-poisoning ability and thermal stability, and enable the catalyst to achieve efficient exhaust gas purification at lower temperatures.        

Optical material applications

Advantages of small particles: In optical materials such as rare earth-doped optical glass and phosphors, small particles of rare earth can be more evenly dispersed in the matrix material, reducing light scattering and improving the transparency and luminous efficiency of the material. For example, the small particle size of rare earth materials used in lighting sources, projection TV phosphors, etc. can help improve their luminous performance and color performance.
