摘 要：Scandia stabilized zirconia powder（Sc SZ） 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 Sc SZ powder was prepared by microwave-heating to 150 oC and 2.5 h. The structure of the Sc SZ 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.
