Al-Zn system has positive heat of mixing. High energy ball milling has been employed to produce four alloys of Al with 2.5 to 10 wt% Zn.

A green method for production of nanobiochar by ball

2017-10-15  Ball milling is a top-down approach for production of nanoparticles in which mechanical forces are used to reduce the size of particles (Deguchi et al., 2006). This method has been widely studied in recent years and it has the potential for green, reproducible, low-cost and large-scale production of different classes of nanopowders ( Charkhi et al., 2010 ).

solvents. The high-energy ball milling was used to reduce the size of graphite particles and induce mechanical energy of milling into elastic energy and defects in the powders. Therefore, the free Gibbs energy of nanocrystalline graphite will increase through the milling process. The storage energy of mechanically activated graphite resulted from the induced defects and structural disorder during the milling condition. Then, separating the graphite layers to obtain expanded graphite in HF solution can be easily achieved. Several studies have been conducted in the field of co-ball milling graphite and solid polymers [17, 18]. Sun et al. prepared expanded graphite by dry ball milling of graphite with cellulose. They have found that the dry ball milling graphite
