Notes:
Highly dense Y2O3 ceramics have been fabricated by a magnetic pulsed compaction(MPC) which is capable of reaching a sufficiently high pressure (~1GPa) in a very short duration (afew microseconds), and a subsequent pressureless sintering at 1600℃. The Y2O3 green bodies witha relative density of about 68% were achieved by the application of the MPC process due to theeffect of an enhanced rearrangement and a high speed movement of the particles, without the helpof ceramic binder. Those compacts showed densities greater than 95%, which is very close to thetheoretical density, after the subsequent pressureless sintering process at 1600 oC. The shrinkagerates of the diameter for the samples compacted by the MPC process were markedly reduced, whencompared to those for the ones by the conventional compaction (CC) process
