CNT dispersion is fabricated by various methods such as sonication [17, 18], centrifugal mixing, high speed stirring, and ball milling . These fabrication methods successfully disperse single wall or multiwall CNTs in various liquid medium such as water, organic solvent, and ionic liquid.
Ball Milling Ball milling and subsequent annealing is a simple method for the production of CNTs. Although it is well established that mechanical attrition of this type can lead to fully nano porous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders by thermal annealing.

Schematic view of CNT growth on catalyst particles during CVD. First, small secondary catalyst particles of the size of a CNT diameter develop, on which the nanotubes start growing. The catalyst particle is either at the top or at the bottom of the emerging nanotube.
It is a ball milling process where a powder mixture placed in the ball mill is subjected to high-energy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960.
For Al-CNTs composite low energy ball milling is suitable method for fabrication. The basic overall process steps consist of mixing of CNTs with aluminum powder by grinding or mechanical alloying, followed by compaction consolidation and sintering, cold isostatic pressing, hot isostatic pressing, or spark plasma sintering.

Ball Milling method for synthesis of nanomaterials, Steps in ball milling method; 1 As the name suggests, the ball milling method consists of balls and a mill chamber Therefore over all a ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum)
Carbon nanotubes reinforced pure Al (CNT/Al) composites were produced by ball-milling and powder metallurgy. Microstructure and its evolution of the mixture powders and the fabricated composites were examined and the mechanical properties of the composites were tested.
Preparation the Al-CNT at milling time about 30 to 100 min, rotational speed is about 300-600/rpm.the wt% of CNT is 0-5%, Analyzed the XRD patterns、SEM and STM micrograph, the results showed the Al material could be reinforced by CNT using HEM. the hardness of Al-CNT is 75 HB and the density is 2.65 g/cm3 when milling 90 min and CNT 3%.
