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.

On April 15th, the 135th Canton Fair, also known as the China Import and Export Fair, kicked off with the theme of “Promoting High-Quality Development and Building a High-Standard Open Platform”. This year's fair is held in three phases, with the last phase ending on May 5th. As one of the most significant international trade events globally, the Canton Fair attracts thousands of companies every year to showcase their latest products.

SAT NANO has recently completed an export order — shipping 2KG of high-purity Titanium Nitride (TiN) powder to a Japanese client. This marks another milestone in SAT NANO's continued expansion across the Asia-Pacific advanced materials market.

In the preparation of oxide powders, specific surface area is a very important indicator, which directly affects the performance and application of the powder. However, the specific surface area is influenced by many factors, the most important of which is the preparation method. Different preparation methods can lead to differences in the size, shape, and porosity of powder particles, which in turn affect their specific surface area. Therefore, when choosing a preparation method, it is necessary to select the appropriate process based on specific application requirements.

Particle rearrangement and densification: In liquid-phase sintering, the generation of liquid phase and particle rearrangement are key steps in densification. Small particles have a large specific surface area and surface energy. After the liquid phase is generated, the solid phase is wetted by the liquid phase and infiltrates into the gaps between particles. If the amount of liquid phase is sufficient, the solid phase particles will be completely surrounded by the liquid phase and approximate a suspended state. Under the surface tension of the liquid phase, they will undergo displacement and adjustment of position, thus achieving the most compact arrangement. At this stage, the density of the sintered body increases rapidly
