When making certain products, such as paints, coatings and electronics, it is necessary to use nanopowders. However, these powders can be difficult to disperse and can clump together, causing issues with product quality. To combat this problem, dispersants are used to effectively separate and disperse these powders. In this article, we will discuss the use and benefits of dispersants for the dispersion of nanopowders.

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

Silicon dioxide SiO2 often has a decisive impact on the performance of systems, whether it is silicone rubber, thin films, or electronic packaging materials.

​The use of nanotechnology has revolutionized the world. One such remarkable feat is the reduction of particle size of Titanium Dioxide powder to nanometers. Nanometer-sized particles of Titanium Dioxide are called Nano Titanium Dioxide Powder. Nano Titanium Dioxide Powder is becoming increasingly popular because of its unique properties and its applications in various fields.

The combination of flexibility and elasticity makes elastic materials essential in a wide range of industries, including automotive, construction, and consumer goods. Moreover, they are increasingly attractive in emerging fields such as microfluidics, soft robotics, wearables, and medical devices. However, having sufficient mechanical strength is a prerequisite for any application. Thus, solving the seemingly contradictory attributes between softness and strength has always been an eternal pursuit.

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.
