zirconia balls as milling media, unfortunately, only 15% product was observed (Table 1, entry 1). We speculated that the lightweight of zirconia balls subjected BaTiO 3 to lowerimpact mechanical collisions thus failed to provide sufficient mechanical impact to activate the BaTiO 3. This result also suggests ball milling is not only mixing ...

The use of ball milling to obtain cellulose nanocrystals was also explored by the group of Yu, who extracted CNCs from ballmilled wood via a multistep process. 40 DouglasFir wood chips were firstly hammermilled to wood flours, which were then treated using a planetary ball mill at 270 rpm. This process was followed by enzymatic hydrolysis and treatment with sodium sulphites.
