| dc.description.abstractEn | Spark plasma sintering of nanocrystalline γ-Al2O3 at very high pressure was investigated up to 5 GPa. A SPS pressure/temperature diagram of α-Al2O3 and γ-Al2O3 phase was plotted. An in-house high pressure spark plasma sintering equipment (HP-SPS) was used. The capabilities and parameters control of this equipment greatly reduced the phase transition and sintering temperatures to obtain ceramics in contrast to conventional high pressure and high temperature sintering (HP-HT). The transition temperature could be lowered to ~500 °C from 1 GPa. The grain growth in ceramic was retained by the HP-SPS sintering. The density was also demonstrated to be optimized with HP-SPS. | |
