375.13 g (1 mol) of aluminum nitrate hydrate [Al(NO3)3.9H2O, manufactured by Wako Pure Chemical Industries Ltd., guaranteed reagent] was dissolved in 777.87 g of pure water, to obtain 1000 cm3 of an aluminum nitrate aqueous solution. To 100 cm3 of the aluminum nitrate aqueous solution was added 2.83 g of the above-mentioned seed crystal slurry (Al2O3 amount: 0.566 g), further, 2.64 g of ammonium nitrate [NH4NO3, manufactured by Wako Pure Chemical Industries Ltd., guaranteed reagent] was added to obtain a compound. 100 parts by weight of this compound contained 10 parts by weight of alumina [Al2O3] as a seed crystal, in terms of Al2O3. The concentration of a nitrate ion (NO3−) in the compound was 3 mol per mol of the total aluminum (Al) contained in aluminum nitrate and seed crystal.
