実験手順

An aqueous solution of 2.0 kg of aluminum nitrate nonahydrate, 1.5 kg of magnesium nitrate and 0.27 kg of 60% nitric acid dissolved in 3.0 L of pure water was prepared. The aqueous solution was gradually added dropwise to 10.0 kg of a silica sol solution (trade name “Snowtex N-30” manufactured by Nissan Chemical Industries Ltd., SiO2 content: 30% by mass) kept at 15° C. with stirring and having a colloidal particle size of 10 to 20 nm, so as to give a mixed slurry of a silica sol, aluminum nitrate and magnesium nitrate. Thereafter, the mixed slurry was kept at 50° C. for 24 hours for aging. The aged mixed slurry was cooled to room temperature and was spray dried with a spray dryer with an outlet temperature set to 130° C. to obtain a dried substance.
