Dec 14, 2004· The first way is to start with a bulk material and then break it into smaller pieces using mechanical, chemical or other forms of energy (top-down). An opposite approach is to synthesize the material from atomic or molecular species via chemical reactions, allowing for the precursor particles to grow in size (bottom-up).
In particular, mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2, N 2 in rare gases) can be problems for high-energy ball milling. However, using optimized milling speed and milling time may effectively reduce the contamination.

Apr 29, 2011· In this new method a magnet is placed close to the cell to apply a strong magnetic pulling force on the magnetic milling balls, and therefore the impact energy is much higher than the conventional ball milling energy. In addition, different milling actions and intensities can be achieved by adjusting the cell rotation rate and the magnet position.
A milling method (P-milling) combining mechanical milling and dielectric barrier discharge plasma were established by them.They reported that the metal powder prepared by P-milling had a lump-like morphology with very high specific surface area. The lump- like powders were agglomerate of fine primitive particles.
preparation techniques of Bottom-up approach have been developed. Figure 2.1 Schematic representation of Bottom–up and Top–down technique The nanostructured materials have been synthesized by different methods including inert gas condensation, mechanical alloying, spray conversion processing, plastic deformation, electro deposition, rapid
Nanotechnology is an advanced technology, which deals with the synthesis of nano-particles, processing of the nano materials and their applications. BALL MILLING Ball milling is a method of production of nano materials. This process is used in producing metallic and ceramic nano materials.

These methods involve synthesis of nanoparticles by top down method. These strategies involve physical breaking of the source material through high energy processes. Mechanical Milling: This involves breaking of bulk material (in microdimensions) to nanoscale with strong mechanical shear forces applied by millng technique.
