- ball milling sol gel
Ball milling is a method of production of nano materials. This process is used in producing metallic and ceramic nano materials. These mills are equipped with grinding media composed of wolfram carbide or steel. Ball mills rotate around a horizontal axis,partially filled with the material to be ground plus the grinding medium.

Nanosized Zn 2 SiO 4 :Mn powders were prepared by two different methods: a high- energy ball-milling of microcrystalline powder (so-called "top-down") and a sol-gel method ("bottom-up"). It was shown that it is possible to obtain particles of 30±10 nm by means of the ball-milling. A particle size of the Zn 2 SiO 4:Mn synthesized by the sol-gel method ranged from 20 …

12%A modified sol–gel method was developed by incorporating additional ball-milling step where dry gel was ball-milled with the additives of synthetic graphite and carbon black. The results show that the LiFePO 4 /C synthesized by the modified sol–gel method has pure phase composition, much smaller particle size and better high rate capability.

The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling ...
