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.

Chemical Total Element Analysis (ICP-MS) is a widely used instrument technology in the field of chemical analysis. It is developed based on inductively coupled plasma mass spectrometry (ICP) technology.

In this blog, we will delve deeper into the world of Germanium nano-powder and explore its numerous benefits.

In the world of powders, particle size is one of the key indicators for measuring their performance. Let's talk about an important concept - D50.

Silver coated copper technology is a composite metal material technology, and its core product silver coated copper powder is composed of copper in the core and silver shell covering its surface. A typical silver layer thickness is between 50-200 nanometers, with a silver content (mass ratio) of 5% -30%. In this structure, the copper core plays a role in providing low cost and high conductivity, while the silver shell is crucial in ensuring that the particles resist oxidation during processes such as pulping and printing, while forming good ohmic contact with the battery silicon wafer or TCO film. After sintering, the silver shell acts as a conductive medium, ensuring low contact resistance and reliable adhesion of the electrode, while the copper core reduces material costs while endowing the slurry with certain mechanical strength and thermal stability.

Infrared spectroscopy: It looks at how much light has been consumed. When a molecule absorbs light of a specific wavelength, we know what functional groups are inside it. Raman spectroscopy: It looks at how much light has been deflected. A laser beam is applied to analyze how much the light bounced back has changed, in order to determine the molecular structure.
