J Nanosci Nanotechnol. 2009 Jan;9(1):342-9.Al2O3-TiO2 bulk gels prepared from aluminum tri-sec-butoxide and titanium tetra-n-butoxide were mechanochemically treated using a planetary, high-energy ball mill. The initial state of the gels was amorphous and a novel crystalline material with a composition of approximately the same atomic ratio of Ti and Al was formed in the gel matrix at around room temperature during the milling. The size of the crystallites was several tens nanometers and their structure probably has a polytypic character with a high density of stacking disorder. Read More
