nature of the milling material [32], and milling speed and time [33] are crucial variables. An appropriate ball-to-powder weight ratio (B/P) is another critical parameter in high-energy ball milling. A high B/P sees more ball-to-ball impact and inefficient milling [24], while a very low B/P from overfilling reduces grinding [34].
