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,

which deals with the synthesis of nano-particles coated with n-Al 2 O 3 by supplying a second precursor in a second stage of reactor. The process yields quantities in excess of 20 g/hr.A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. The term is sometimes used for larger particles,
