When it comes to powdered materials, density is an essential parameter that determines their physical and chemical properties. Different methods are employed to measure powder density, including loose bulk density, tapped density, true density, apparent density, bulk density, and compacted density. This article will discuss these parameters, and how they affect the properties of powdered materials.

​As the world progresses, materials' limitations hinder advancements in multiple industries. This is where nanotechnology comes into play, as it offers a microscopic solution to enhance materials and generate innovative applications. One prominent example is the Nanometer-sized ATO Powder 20nm provided by SAT NANO. This effectively improves materials' performance, bringing about improvements to various industries.

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:

The passivation layer of metal nanoparticles refers to a thin film or protective layer coated on the surface of metal nanoparticles. It usually consists of a compound, such as an oxide, sulfide, or organic compound. This passivation layer can alter the surface properties of metal nanoparticles and provide protection and stability.
