Spherical particles of lanthanide zirconates Ln(2)Zr(2)O(7) (Ln=La,Nd,Dy) were prepared by an aqueous inorganic sol-gel route. Characterisation was by X-ray diffraction, scanning electron microscopy, differential thermal analysis, thermogravimetric analysis and complex impedance spectroscopy. Calcination of the gel spheres at 750 degrees C produced fully crystalline fluorite phases. Further calcination above 850 degrees C produced pyrochlore phases with La and Nd. Activation energies and pre-exponential factors were calculated from complex impedance curves obtained in the temperatures range 570-1000K.
