    The effects of precipitants on co-precipitation synthesis of yttria-stabilized zirconia nanocrystalline powders

    Yttrium-stabilized zirconia (Y0.08Zr0.92O1.96, YSZ) nanocrystalline powders were prepared by co-precipitation methods. Different precipitants (ammonium hydroxide, ammonium bicarbonate, oxalic acid, and urea) were...
