Zinc oxide nanoparticles were synthesized by K Vojisavljevic et al[121] by milling in a planetary ball mill with a zirconia milling assembly for up to 5 h in air. The deviation of the lattice parameters from single crystal values was related to defect creation and increase of strain inside the hexagonal lattice of milled ZnO nanoparticles.

High-energy ball milling is a convenient way to produce nanosized powders. It is the most common method reported in the literature for the synthesis of intermetallic nanoparticles. Before a mechanical milling is started, powder (s) is loaded together with several heavy balls (steel or tungsten carbide) in a container.

Disperse nanoparticles: 1. If used in the aqueous phase, may use ultrasonic treatment to disperse; 2. If used in oil phase, may use high shear mixing instrument to disperse. 3. If directly used as dry powder form, may use ball mill treatment to disperse. How to disperse nano-materials and mix with other powder?

Ball milling is a grinding method that grinds nanotubes into extremely fine powders. During the ball milling process, the collision between the tiny rigid balls in a concealed container will generate localized high pressure.

Advantages of ball milling process: 1. Nanopowders of 2 to 20 nm in size can be produced. The size of nanopowder also depends upon the speed of the rotation of the balls. 2. It is an inexpensive and easy process. Disadvantages; 1. As the process is not so sophisticated, therefore the shape of the nanomaterial is irregular. 2.

Preparation of ROSCa nanoparticles . ROSCa nanoparticles were prepared in two steps. ROSCa powder was first subjected to dry milling using planetary ball mill (Pulverisette 7 Premium, Fritsch Co. Germany), in order to decrease the particles size to less than 20 µm. since the received raw material was analyzed for particle size and it was found 618 µm.
