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.

Boron nitride has excellent properties such as high temperature resistance, oxidation resistance, chemical corrosion resistance, and neutron absorption, and has low dielectric constant and dielectric loss.

On unsaturated metal sites of metal oxides or semiconductor oxides (such as Ti4+, Fe3+), water molecules first adsorb in molecular form, followed by O-H bond cleavage, resulting in bridge or terminal hydroxyl groups (M-OH) and surface hydrogen atoms. The thermodynamic driving force of this process comes from the strong Lewis acidity of metal ions, making water molecules easy to dissociate. Both experiments and DFT calculations indicate that surfaces covered with low oxygen tend to dissociate and adsorb, while surfaces covered with high oxygen tend to adsorb molecules.

At just a fraction of the size of traditional copper powders, our nano metal copper powder boasts an incredibly high surface area-to-volume ratio, which makes it an ideal choice for a variety of industrial and technological applications.
