Fabrication of Hydroxyapatite Tantalum Composites by

The conventional powder metallurgy method was selected to prepare HA/Ta composites. A planetary ball mill was used to mix and mill the 90% HA powder (99.9%, d (0.5) = 39.8 μm) and the 10 wt % Ta powder (99.9%, d (0.5) = 122.5 nm) at a speed of 250 rpm for 2 h. Moreover, extra 2 wt % hydroxypropyl methyl cellulose (HPMC) was selected as a binder.
