摘要：

Alumina-10% wt cerium oxide composite powders are prepared through the citrate polymer precursor route under two conditions. The thermal decomposition characteristics of the precursors, average particle size, tap density, compaction behaviour, surface morphology, as well as the point of zero charge of the two powders, are reported. The acid citrate derived powder has a density of 0.87 g/cm3 while that derived from amorphous citrate is only 0.58 g/cm3. The compaction density of this powder at 200 MPa is also lower by 4% compared to the former, but could be raised further by addition of 3% polyvinyl alcohol as binder.
