A transparent [Al13O4(OH)24(H2O)12]^7+ solution is produced by reacting it at 60~70 °C for 8~12 hours after adding 0.4M NaOH aqueous solution to 0.4M AlCl3.6H2O aqueous solution. It is aged for 9~11 hours at the room temperature after mixing a colloidal solution manufactured by expanding clay in distilled water and the [Al13O4(OH)24(H2O)12]^7+ solution. The alumina(Al2O3) pillared clay precursor is generated by drying it at 50~70°C after filtering obtained precipitate and washing the distilled water and removing a Cl^- which is a counter ion with a non-reactive Al^3+ ion. The clay in which NH4+-Al is cross-linked is produced by treating it with NH3 steam vapor after calcining a generated alumina(Al2O3) pillared clay precursor at 350~450°C for 3~5 hours and producing alumina-pillared clay. The aqueous solution of the metallic ion prepared in advance is mixed with the clay in which the generated NH4+-Al is cross-linked. After aging it at a room temperature for 13~17 hours and filtering the obtained precipitate, it is washed by distilled water at 40~60 °C, dried at 50~400 °C for 3~5 hours, heat-treated at 300~600 °C, and alumina-pillared clay in which a metallic ion is mixed is obtained.
