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.

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.

Nanopowders have become a crucial element in the manufacturing industry, particularly in the production of high-performance materials. One of the properties that make nanopowders valuable is their thermal conductivity. In this article, we will explore the different types of nanopowders with thermally conductive properties that can be used in various applications.

Magnesium oxide nanopowder refers to a form of magnesium oxide that has been synthesized at the nanoscale. Nanoparticles are particles with dimensions in the range of 1 to 100 nanometers (nm). Magnesium oxide (MgO) is a compound composed of magnesium and oxygen atoms.

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.
