Translucent Dy3+ doped α-SiAlON ceramics were successfully fabricated by the gas pressure sintering (GPS) method. The efficacy of this sintering technique also the affects initial particle size on densification, final microstructure and optical properties of GPS-ed Dy-α-SiAlON ceramics, all of which are discussed. Two types of starting powder mixtures were prepared using different milling procedures...
Transparent Y2O3 ceramics were fabricated by the solid-state reaction and vacuum sintering method using La2O3, ZrO2 and Al2O3 as sintering aids. The microstructure of the Y2O3 ceramics sintered from 1550°C to 1800°C for 8h were analyzed by SEM. The sintering process of the Y2O3 transparent ceramics was optimized. The results showed that when the samples were sintered at 1800°C for 8h under vacuum,...
