Comminution of silicon carbide powder in a planetary mill

These data pointed out that the planetary milling operation worked well on breaking large particles but not the submicrometer ones, since the peak centered at 0.2 μm kept steady during the whole period. Also, for the milling conditions used, the value of 0.2 μm can be considered as a threshold value, below which particles cannot be broken.
