    Structural and Textural Modifications of ZrO2 Induced By La2O3 Addition, Thermal Treatment and Reducing Process

    Lanthana-doped zirconium oxide may strongly influence the solid state reaction. A series of samples denoted ZrxLa1–x (where x = atomic percentage of the element) are prepared by hydrolysis in the neutral medium f...
