​Metal nanopowder is an innovative material with a wide range of applications in various industries. As one of the leading manufacturers of high-quality metal nanopowders, SAT NANO is committed to providing the best products to our customers. In this article, we will explore the question of why metal nanopowder appears black.

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.

​As a leading provider of high-quality PVP-coated nanoparticles, SAT NANO understands the need to remove PVP coating for various applications. PVP or polyvinylpyrrolidone is a polymer widely used to coat nanoparticles due to its superior solubility and stability. However, the PVP coating can interfere with the nanoparticles' surface reactivity, causing challenges in some applications. This article will discuss the different methods to remove PVP coating from PVP-coated nanoparticles.

Advanced ceramic materials, as an important component of new materials, are not only widely used in high-tech fields such as communication, electronics, aviation, aerospace, and military, but also have rapidly developed in the semiconductor and new energy industries in recent years, becoming the most promising application field for the next generation of advanced ceramic materials.

​Transmission electron microscopy (TEM) is an indispensable research tool in fields such as materials science and nanotechnology. For researchers who are new to TEM, understanding its basic principles and operations is crucial for efficient utilization of this equipment. TEM testing mainly focuses on the microstructure characteristics of materials, including element distribution, phase composition, crystal defects, etc. These characteristics are manifested at the microscopic level as the size, shape, distribution of different phase grains, as well as the density and distribution of crystal defects. Through TEM, researchers can gain a deeper understanding of the internal structure of materials, thereby evaluating their properties and potential applications.

Let's use an example to illustrate how to dilute the nano silver dispersion: Assuming you have a sample containing a nano silver dispersion with a concentration of 100 mg/mL, you would like to dilute it to 10 mg/mL. You are preparing to use deionized water as a diluent solvent.
