The main objective of this work was investigate the effect of ball milling on microcrystalline cellulose (MCC) structure. FTIR results shows there are no obvious different in the function groups of between neat and ball milling MCC. Both FTIR and WAXD analysis indicate that the crystalline of MCC samples are change with the ball milling time.

Effect of ball milling on structure and thermal stability ...

The influence of ball milling on microstructure and thermal stability of the gas-atomized Al 84 Gd 6 Ni 7 Co 3 glassy powder has been investigated as a function of the milling time. The results show that the traces of crystalline phases present in the as-atomized powder decrease gradually with increasing the milling .
