Rare earth nanomaterials have unique physical and chemical properties, and their applications are very wide, including petrochemicals, material development, ceramics, catalysts, permanent magnet materials, luminescent materials, environmentally friendly materials, biomedicine, hydrogen storage and other fields. The particles of nano-level rare earth products are aggregates composed of very few atoms or molecules with regular microstructures inside[1]. The size and shape of nanomaterials play a decisive role in the performance of the material, as a result, the ability to control the particles of rare earth nanomaterials has a very important meaning for the improvement of the performance of the material.
RARE EARTH
Our Services
Rare earth nanoparticles, which maintaining their original physical and chemical properties, and exhibit special properties in electricity, magnetism, mechanics and optics. They are widely used in ceramics, permanent magnet materials, luminescent materials and catalysts. The size of nanoparticles is different, and their performance is also very different. Alfa Chemistry is aiming at the characteristics of rare earth nanomaterials, a variety of methods and monitoring equipment are used to control the size of nanoparticles to conduct function-oriented synthesis. The services provided by the design of rare earth powder nanomaterials include but are not limited to:
❖ Particle information analysis and testing
❖ Granularity control scheme design
❖ Granularity control scheme analysis and improvement
❖ Synthesis of specific size samples
RARE EARTH
The meaning of granular control
Many polymer materials are not only affected by molecular properties (molecular weight, molecular structure, molecular weight distribution), but also have a great relationship with molecular morphological characteristics (particle surface morphology, particle size distribution, particle size). Generally speaking, the smaller the particle size, the better its catalytic performance and optical performance. However, the smaller the particle size, the agglomeration is likely to occur, resulting in a decrease in performance[2]. The particle size can be adjusted in an appropriate way to achieve Play a control over material performance. Therefore, the particle size control and design of powdered nanomaterials are of great significance.
