Particle Parameters

For rare earth materials in powder form, such as rare earth oxides, rare earth salts, rare earth catalysts, rare earth phosphors et al, the characteristics of the particles have the very important influence on the properties of the material. The smaller the particle size, the more uniform the distribution, and the active sites The more, the performance of the material may be better[1]. The physical parameters of powder materials mainly include particle size, dispersion, surface area, fluidity, particle size, particle diameter et al. Alfa Chemistry can provide professional particle testing services for rare earth powder products, with a strong scientific research team, and the use of advanced testing the equipment can provide scientific, fair and accurate testing data and provide customers with a full range of testing services.


Our Services

Powder materials are widely used in production and life. In different fields, the requirements for powder materials are not used, and the importance of particle parameters is also different. Particle analysis is an important means to characterize powder materials, and can reveal the special properties of materials from a microscopic perspective. The ability to classify and analyze the parameters of the particles of the material is of great significance in production and life. Alfa Chemistry can provide micro-particle testing services, which can analyze special parameters according to different industry needs, and can make reasonable improvements and suggestions. The services we can provide include but are not limited to:

❖ Particles parameter selection

❖ Particles parameter analysis

❖ Quality control

❖ Product diagnosis
