Compaction of ZrO₂(Y₂O₃) Powders with Different Particle Sizes and Effects on the Sintering

Abstract:

In this work, compacting powders of different ZrO₂(Y₂O₃) are investigated relating the particle size, compaction pressure, and use of binders. Powders of ZrO₂ stabilized with 3mol % Y₂O₃ with an average particle size of 0.15 to 0.7μm presence of both bonding and 0.15μm without addition of binder, were uniaxially compacted with pressures of 30 to 115MPa. Green density between 40% and 50% were obtained. The results indicate that powders sized less densification above 1400°C, while the larger sizes only after reaching full densification above 1500°C. Crystallographic characterization indicates that the powders have a percentage of monoclinic phases in the range of 15% to 26%, but only after sintering tetragonal phase is identified.
