Abstract
The thermal evolution of three different aluminosilicate gels of mulli te composition, Al6Si2O13, synthesised by colloidal and polymeric meth ods was studied. The experimental techniques used were N-2 adsorption, measurements of density Hg porosimetry, infrared absorption spectrosc opy, TEM, and XRD. Changes in specific surface area and density of gel s with temperature are discussed in terms of phase evolution and the m ethods of gel preparation. (C) 1998 The Institute of Materials.
