Procedure

An aqueous solution in which 3.75 kg of aluminum nitrate nonahydrate, 2.56 kg of magnesium nitrate and 540 g of 60% nitric acid were dissolved in 5.0 L of pure water was gradually dropped into 20.0 kg of a silica sol solution having a colloidal particle diameter of 10 to 20 nm while stirring and holding at 15° C. (Nissan Chemical Industries, Snowdex N-30, SiO2 content: 30% by mass) to obtain a mixed slurry of silica sol, aluminum nitrate and magnesium nitrate. Subsequently, the mixed slurry was aged by holding at 50° C. for 24 hours. After cooling to room temperature, the mixed slurry was spray-dried with a spray dryer set to an outlet temperature of 130° C. to obtain a solid.
