Milling of Porous Silicon Microparticles SpringerLink

While changes in shape have been reported for porous silica particles after ball-milling, transforming from either modular or acicular to spherical (depending on the size range), milled porous silicon microparticles retain the acicular shape to some degree; being more brittle and mechanically softer, less aggressive milling conditions are required to achieve comparable sizes (Heikkila et al. 2009); the use of
