Bulk gels corresponding to an oxide composition of 3A1203.2Si02, prepared from a sol with a high solids yield using submicron alumina powder and colloidal silica sol as precursors, were sintered to over 99% of theoretical density after 2 h at 1300ยฐC. Denstfication occurred by viscous flow of the amo
