Transformations in oxides induced by highenergy ballmilling

High energy ballmilling of oxides is more and more currently used to activate powders and to prepare nanooxides at moderate temperatures. The interest of an activation step is well illustrated by the broad development of doped titania powders, synthesized by heat treatment of preground reactants, for photocatalytic applications or to develop antibacterial materials.

Hightech Ball Mills Spur Nanotechnology Advances

When the sun wheel turns, every grinding jar rotates around its own axis, but in the opposite direction. Thus, centrifugal and Coriolis forces are activated, leading to a rapid acceleration of the grinding balls. The result is very high pulverization energy, allowing for the production of very fine particles.
