摘      要：Scandia stabilized zirconia powder （ScSZ） was first synthesized by a microwave-hydrothermal method. The crystalline and aggregated particle sizes were investigated by means of X-ray diffraction （XRD）, Raman, scanning electron microscopy （SEM） and transmission electron microscopy （TEM）. Weakly agglomerated and well crystallized ScSZ powder was prepared by microwave-heating to 150 ℃ and 2.5 h. The structure of the ScSZ powder changed from a tetragonal to a cubic phase, and accordingly, the powder conductivity was increased from 90.55 to 120.56 ms/cm by the introduction of the mineralizer solutions （KOH＋K2CO3） during the microwave-hydrothermal processing.
