The knife ground sample was used in order to facilitate the grinding process in cryogenic or ball mill. Cryogenic grinding was performed in a cryogenic mill (Spex model 6800, USA) with a selfcontainer liquid nitrogen bath. The precooling time was 5 min and grinding times were in the range from 10 to 50 min (525 cycles of 2 min grinding).
