As one of the most important characterization parameters of nano powder, particle size directly affects the physical and chemical properties of the powder, and then affects the performance of the final product. Therefore, its detection technology is an important tool for industrial production and quality management, and plays an irreplaceable role in improving product quality, reducing production costs, and ensuring product safety and effectiveness. This article will start from the principle and compare three common methods for powder particle size detection: electron microscopy, laser particle size analysis, and X-ray diffraction line width method, and analyze the advantages, disadvantages, and applicability of different particle size testing methods.

​The preparation of SEM nano powder samples usually requires the following steps:

Nanotechnology has revolutionized the materials industry, and the advent of nanoparticles has further increased its capabilities. Nanoparticles are tiny, but they possess unique properties that differ from their bulk counterparts. Perhaps one of the most fascinating traits of nanoparticles is their ability to exhibit optical properties. In this article, we will discuss the nanoparticles that possess optical properties and their potential applications. At SAT NANO, we offer high-quality nanoparticles that have been manufactured to the highest standards.

​Nano silver dispersion has been widely used in various fields such as medical science, electronics, and food packaging. The higher the concentration of nano silver dispersion, the stronger the anti-bacterial properties. However, sometimes it is necessary to dilute the high concentration nano silver dispersion to a lower concentration. This article will guide you through the process of how to dilute high concentration nano silver dispersion to low concentration effectively.

There are different methods to measure the particle size of powders, depending on the size range of the particles and the desired accuracy of the measurement. Here are some common techniques:

Hydroxyl groups (- OH) can exhibit acidity or alkalinity on the surface of metal oxides in the form of proton reception or supply. By adjusting the quantity and distribution of hydroxyl groups, precise control of surface acidity and alkalinity can be achieved, thereby affecting the activation pathway and selectivity of catalytic reactions.
