Abstract
Transparent lutetium oxide (Lu2O3) body was prepared by spark plasma sintering using a two-step pressure profile combined with a low heating rate. The effects of pre-load pressures from 10 to 100MPa and heating rates from 0.03 to 1.67Ks-1 on the microstructures and optical properties were investigated. With increasing pre-load pressures from 10 to 100MPa, the grains became smaller with a narrower distribution, whereas the transmittance showed maxima at 30MPa. The average grain size slightly increased from 0.67 to 0.86μm as the heating rate increased from 0.03 to 1.67Ks-1, while the transmittance decreased. Transmittances of 60% at 550nm and 79% at 2000nm were obtained under a pre-load pressure of 30MPa at a heating rate of 0.17Ks-1.
