The effects of grinding of Al2O3was carried out by planetary ball mill when carbon nanotube was added as additive to investigate how the two material affect each other according to the rotation speeds. For grinding media ball, Ø3 mm zirconia ball was used and its rotation speed were 100, 200, 300, 400, 500 rpm. To compare the results of grinding of combination of Al2O3 and carbon nanotube, grinding of Al2O3 and carbon nanotube were done as well respectively. The grinding of carbon nanotube showed that the size were decreased on mill's rotation speeds and there seems that some carbon nanotubewas coated on the surface of Al2O3 on the combination grinding and with XRD measurment, the grinded Al2O3 has changed to be some amorphous. |
