Nanoparticles formation by ball mill grinding

Jan 18, 2021 A detailed investigation is presented for the solvent-free mechanochemical synthesis of zinc oxide nanoparticles from ε-Zn(OH) 2 crystals by high-energy ball milling. Only a few works have ever explored the dry synthetic route from ε-Zn(OH) 2 to ZnO. The milling process of ε-Zn(OH) 2 was done in ambient conditions with a 1:100 powder/ball mass ratio, and it produced uniform ZnO
