Synthesis and characterisation of submicron silica ...

Increasing the milling time (from 0 to 72 h) reduces significantly the particle size in C18, C36 and C72 samples, because the system is subjected for longer to the collisions, intensive fracturing and welding generated in the milling process. Mechanical ball milling is shown to be effective for reducing the particle mean size of the silica.
