Preparation of sol. When the gel was formed, it was dried at 100 C for 72 h. The xerogel was calcined at 500 C for 1 hour and the heating rate was fixed at 5 C/min. Obtained powder was milled (planetary ball mill, Retsch PM 400) for 1 or 6 hours for particle homogenization. Size distribution of (over 1000 C) of calcination or sintering is required for preparation of solid solu-tions of zirconia with these oxides 46.
