This study investigated the effect of planetary ball mill parameters on the   particle size of a powder mixture of alumina and magnesia, the composition of   synthetic magnesium aluminate spinel (MAS), and the subsequent densification   of MAS. The results show that the particle size of the milled powders   decreases gradually from 32.39 μm to 11.69 μm with the increase of milling   time from 1 h to 7 h at milling speed of 120 rpm. The particle size of the   milled powders decreases gradually from 42.92 μm to 9.00 μm as the milling   speed was increased from 60 rpm to 240 rpm at a milling time of 3 h. Only a   spinel phase can be obtained from these calcined powders when the starting   powders of the calcined powders are milled for more than 1 hour or at above   60 rpm. The relative density and flexural strength of the sintered products   exceed 86.67% and 105 MPa, respectively

Influence of parameters of high-energy ball milling on the synthesis and densification of magnesium aluminate spinel
