Abstract
The inhibitory effect of the mixed alumina and silica additives with m olar ratios of [Al]/[Ti] = 0.05 and [Si]/[Ti] = 0.05 on the phase tran sformation of anatase to rutile was investigated. The suppressing effe ct on the anatase-rutile transformation by the mixed additives was obs erved to be much stronger than that of the single additive. The format ion of the anatase solid solution with both alumina and silica was pro bably responsible for the stronger inhibitory effect. (C) 1998 Elsevie r Science B.V. All rights reserved.
