Ball milling as a mechanochemical technology for …

Another Fe-biochar composite was synthesized via ball milling and achieved 97.8% removal of Cr(VI) in acidic conditions (Wang et al., 2020b). Ball milling was found to enhance the combination of Fe 0 and biochar, decease the hydrodynamic diameter, and introduce abundant acidic functional groups which contributed to the complexation of Cr(VI).

Microstructures and mechanical properties of B4C-TiB2

After 12 h ball milling treatment, the particle size of the powder mixture decreased from 2.06 μm to 1.21 μm, when the ball milling time increased to 24 h, the particle size only decreased from 1.21 μm to 0.96 μm. It is evident that the ball milling effect was significant before 12 h, and became weaker between 12 and 24 h.
