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...

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...

In order to obtain the correct data of the primary particle size, it is often necessary to open the agglomerated particles in the particle size test to form a particle monomer and keep it uniformly dispersed in the medium. This operation is called "dispersion". The requirement of the laser particle size analyzer for the dispersion system is "dispersion without segregation". Dispersion techniques a...

Manganese dioxide (chemical formula: MnO2) is a black or brown solid, the most stable oxide of manganese, and is often found in pyrolusite and manganese nodules. Pylusite is the main mineral containing manganese; manganese nodules (submarine rock solids) also contain manganese. Manganese dioxide is mainly used to make dry batteries, such as carbon-zinc batteries and alkaline batteries; it is also ...
