Description
Yttria stabilized zirconia powders were synthesized by the reverse microemulsion method. Powders were calcined from 600 degrees C to 1000 degrees C and sintered at 1450 degrees C. Crystalline properties and microstructure of samples were characterized by X-ray diffraction and scanning electron microscopy, respectively. Oxygen ionic conductivity was measured by electrochemical impedance spectroscopy. Sizes of yttria stabilized zirconia particles calcined at 1000 degrees C are lower than 100 nm, and approximately, 1 mu m grain was obtained after sintering at 1450 degrees C.
