Abstract

The environment of the Al atom in alumina gels, single-phase and diphasic mullite gels, and their transformation products was studied. Heat treatment of gels at 500 degree C caused partial conversion of octahedral Al to tetrahedral Al. The Al in single-phase mullite gel appears to be highly ordered compared to that in diphasic mullite gel.
