The chemical reduction method of silver coated copper powder refers to the process of using a reducing agent to reduce the ions in the main salt to elemental form and depositing on the surface of the substrate with autocatalytic ability in a metastable solution system. When the reducing agent is oxidized on the catalytically active surface, free electrons are generated. These free electrons can re...

Open your mouth and align the teeth with a 3D scan, and the 3D printer can print a zirconia ceramic denture. Before the advent of 3D printing technology, people needed to bite out the dental membrane to make a denture, and then sent it to the factory for production, and repeated carving, the production cycle was longer, and 3D printing technology not only improved efficiency, but also greatly save...

The displacement reaction method is a common process for processing silver-coated copper powder. Because the surface activity of copper powder is very large, it is easy to oxidize, so it must be pretreated before coating the copper powder. 1. Put the required amount of copper powder into the pretreatment tank, and then wash with 15% 30% dilute sulfuric acid to keep the pH of the solution at 3 2. W...

Density is a physical quantity that reflects the properties of matter. The properties of matter refer to a property that matter itself has but can be distinguished from each other. People often feel that substances with high density are "heavy" and substances with low density are "lighter". "Heavy" and "light" essentially refer to the magnitude of density. Density is a property of matter, it does ...

Nanoparticles have a special surface structure, which lacks adjacent coordinating atoms on the surface, and has high activity, so it is easy to agglomerate. Due to the strong self-absorption property among nanomaterial particles, the agglomeration of nanoparticles is inevitable. Aggregates can be divided into two types: hard agglomerates and soft agglomerates. The formation process of agglomerates...

The thermal properties of nanomaterials are inseparably linked to the motion behavior of molecules and atoms in the material. such as the melting point of nanomaterials. The melting point of a solid substance is fixed when its form is large in size. For nanoparticles, due to the small particles, the high surface energy of the particles, the large number of surface atoms, the incomplete coordinatio...
