More Information
Summary:Disclosed are metal oxide having high thermal stability and a preparation method thereof, specifically including continuously reacting a reaction mixture, composed of (i) water, (ii) a first metal salt including an aqueous cerium compound and (iii) a second metal salt including an aqueous aluminum compound, at 200~700° C. under pressure of 180-550 bar, the reaction product having a molar ratio of metal, other than aluminum, to aluminum of 0.1~10.
