N2 - The SPS (Spark Plasma Sintering) process is a new materials synthesis processing technology recently developed by Sumitomo Coal Mining Co.Ltd., Japan. Some oxides such as Al2O3, Y-TZP, YAG, Al2O3-ZrO2 and Mullite were successfully superfast densified by SPS under the conditions of heating rate as high as 600°C/min, no keeping time at the sintering temperatures above 1200°C, and then fast cooling to 600°C within 3 minutes. The superfast sintering samples show high densities, fine microstructures and excellent mechanical properties. The fracture toughness K1c of 20mol% Al2O3-ZrO2(3Y) samples sintered by SPS at >1250°C for 2 min is higher than 6MPa·m1/2. The reaction sintering of ZrO2- mullite could be completed by SPS at 1530°C for 3 min.
