A tetragonal t-(Ce 0.5 Zr 0.5 )O 2 , (t), prepared from ceria and zirconia mixtures by a conventional ceramic method, was reduced at 1123 K and successively oxidized at 873 K to attain a novel tetragonal phase, t meta -(Ce 0.5 Zr 0.5 )O 2 (t meta ). The electrical conductivity t of t meta was measur
