silicon wafers obtained
using powder technology.
Depending on the temperature difference, we can divide the powder into 3 parts. The needle-fiber bundle (1) on the surface with a relatively high temperature is the 2 spheres that separate it from the powder core (3). In the process of mechanical action, the atomic structure of these spheres is radically different from each other. It is difficult to obtain such a structure chemically. As we have seen, nanoparticles with different atomic or molecular structures are formed during dusting.
