Nano Applications - NETZSCH Grinding & Dispersing

Nanoparticles are smaller than viruses and bacteria. Therefore, as a rule, they can easily penetrate cells. This characteristic makes nanoparticles interesting for the pharmaceutical industry, since they can be used to transport "effective ingredients" through biological barriers such as the blood-cerebral barrier for example.

EFFECT OF DRY GRINDING ON KAOLIN MINERALS by - The Clay ...

After further grinding, the structure of the reaggregated particle seems to be zeolitic. Finally, the kaolin mineral thoroughly changes to a completely amorphous substance similar to a silica-alumina mixed gel. Consequently, the effect of dry grinding of kaolin is related to the degree of crystallinity of the original kaolin mineral.
