13 mol% calcia-stabilized zirconia (CSZ) powders were synthesized by the coprecipitation method. The characterization of powders has been investigated using thermogravimetry and differential thermal analysis for thermal analysis, X-ray diffraction and infrared spectroscopy for crystalline phases identification, Brunauer-Emmett-Teller, X-ray diffraction-line broadening and transmission electron microscopy (TEM) for particle size and morphology determination. The characteristics of powders prepared by the coprecipitation method are discussed.
