The factors that affect the forming process mainly include the properties of the powder, the characteristics and effectiveness of additives, and the pressure, pressurization method, and pressurization speed during the pressing process. The properties of the powder mainly include the particle size, particle size distribution, particle shape, and moisture content of the powder. First. The influ...

With the rapid development of modern industry and technology, different industries have increasingly high performance requirements for powder materials. In addition to having extremely low impurity content, fine particle size, and narrow particle size distribution, powder materials also need to have a certain particle morphology. Spherical powders have been widely used in high-end industries such ...

In transmission electron microscopy (TEM) analysis, the primary and crucial step in obtaining a high-quality image that can be interpreted reasonably is sample preparation. Inappropriate sample thickness, poor conductivity, or damage introduced during sample preparation can directly lead to abnormal electron beam penetration, image distortion, and even sample scrapping. TEM sample requirements ① T...
