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.

​Are you familiar with the term nanotechnology? It refers to the science, engineering and manipulation of materials at the nanoscale level. You might be wondering how this technology can be applied to our daily lives. One common application is the use of nanometallic powders, particularly nanometallic molybdenum powder.

​The use of nanotechnology has revolutionized the world. One such remarkable feat is the reduction of particle size of Titanium Dioxide powder to nanometers. Nanometer-sized particles of Titanium Dioxide are called Nano Titanium Dioxide Powder. Nano Titanium Dioxide Powder is becoming increasingly popular because of its unique properties and its applications in various fields.

As an important physical property of powders, specific surface area refers to the total surface area per unit mass of oxide powder. And its size is influenced by various factors. Firstly, particle size is an important factor affecting the specific surface area of powders. The smaller the particles, the larger the specific surface area. This is because the smaller the particle size, the larger the surface area of each individual particle, thereby increasing the total surface area per unit mass of powder.

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.
