The preparation of powders by ball milling usually results in particle refinement and increased specific surface area (Li et al., 2009; Gu et al., 2017). Inversely, the understanding of mechanical pulverization should not only be a simple mechano-physical process but a complex physical-chemical process (Gu et al., 2017; Wang et al., 2022). This ...

Among them, ball milling is more efficient in improving particle size and morphology [45]. Ball milling is an advanced technique used to synthesize various functional materials with improved structure, shape, and crystallinity [46]. It uses mechanical energy from the constant collisions between milling balls and powder particles.
When the ball-milling further proceeds, D ⊥ decreases as the flaky particles fracture into small pieces, H k increases as M s decreases according to Eq. ( 4 ). All these variations lead to the resonance frequency's shifting towards lower frequency and simultaneously a weakened natural resonance, resulting in a decreased permeability in low ...
