Abstract:
In this study, mullite/zirconia composites were synthesized by reaction sintering from zircon, kaolinite and alumina mixtures having colemanite additions (wt. % 7). Prepared mixtures were sintered at 1450, 1500 and 15500C temperatures for 5 hrs. These two mixtures were compared using DTA and XRD analyses according to some physical properties. It was determined through both DTA and XRD analyses that colemanite addition to mullite/zirconia composite synthesis lowers reaction temperature. While zircon in the mixture without colemanite existed up to 1550oC, it decays completely in the composition with colemanite at 1450oC
