Abstract:
The method for the preparation of a synthetic, quasi crystalline inorganic oxide composition which comprises:(a) preparing a first solution of a neutral inorganic oxide precursor;(b) preparing a second solution of a neutral amine template in water and a miscible organic solvent, by stirring it at a temperature between about minus 20.degree. and plus 100.degree. C., wherein the second solution contains a volume excess of the water or the miscible organic solvent relative to each other;(c) mixing of the solutions of steps (a) and (b) at a temperature between about minus 20.degree. and plus 100.degree. C. to form a precipitate which is aged to form the quasi crystalline inorganic oxide composition;(d) separating at least some of the template from the quasi crystalline composition; and(e) optionally calcining the quasi crystalline composition.
