  • Process for producing stabilized alumina having enhanced resistance to loss of surface area at high temperatures
    Patent number: 5837634
    Abstract: A process for preparing a stabilized alumina wherein an aqueous slurry of a precursor boehmite alumina is admixed with an effective amount of a stabilizer such as a water-soluble salt of a polyvalent metal cation of Groups IIA and IIIB of the periodic table, the slurry containing the alumina and the stabilizer being aged at a pH of from about 3 to about 9 and a temperature greater than about 70.degree. C. for a period of time sufficient to convert the greater portion of said alumina to a colloidal sol, the colloidal sol being recovered and calcined to produce a stabilized alumina.
