摘要：
ZrO2 ceramics containing CaO or MgO as an additive were fabricated by the spark plasma sintering (SPS) method and pressureless sintering (PS) method at 1300°C and 1500°C. Sintered samples were characterized by XRD and their microstructures were observed by SEM. Spark plasma sintering resulted in the successful fabrication of tetragonal ZrO2 bulks with fully dense microstructures over 99% of theoretical density, although ones prepared by the pressureless sintering (PS) method had the lower density of 93 %.
