Graphene coated copper and silver coated copper have essential differences in conductivity, each with its own advantages and disadvantages, and their applicable scenarios are also different.
How to prepare the ferric oxide powder Fe3O4 nanopowder? Let's briefly introduce the manufacturing process, and you can also follow this method to make it.
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.
Nano silver powder, as an important functional material, plays an important role in multiple industrial fields due to its unique physical and chemical properties. Among them, 100nm silver powder (silver powder with a particle size of 100 nanometers) has become one of the most widely used specifications due to its excellent performance in conductivity, antibacterial and catalytic properties.
Our research at SAT NANO has identified several critical advantages. First, Boride Nanoparticle additives create a denser, more cohesive barrier against moisture and chemical penetration. Second, they dramatically improve abrasion resistance – often increasing it by 200-300% compared to standard coatings. Third, they maintain stability at temperatures exceeding 800°C, where traditional coatings would rapidly degrade.
When carrying out the airflow crushing process, it is usually encountered that the moisture absorption of the crushed material significantly increases, and it still absorbs water after drying. How to control it.
