The main objective of this article is to obtain polyphasic ceramics belonging to the Al2O3-SiO2-ZrO2 system by reactionsintering of zircon, alumina, kaolinite and colemanite powder mixture was explored in this work. In addition, the study focusedon low temperature synthesis and the mechanical properties of ZTM improved as expected following the addition of boronminerals such as colemanite (Ca2B6O11·5H2O). The effects of sintering temperature, solid concentration of the preparedsuspensions and colemanite additive on the mechanical and other properties of mullite-zirconia composites were investigated. Green compacts were made by slip casting of stabilized aqueous suspensions with and without colemanite additive after whichreaction-sintering was applied at temperatures ranging between 1450 to 1550 oC under different firing conditions. Theresulting sintered materials were characterized in terms of bulk density, XRD and SEM and and mechanical properties suchas flexural strength, elastic modulus, hardness and fracture toughness. It was observed as a result of a comparison betweenthe mullite-zirconia composites prepared via slip casting and studies in literature from a mechanical standpoint thatcomposites in literature have yielded similar results in terms of mechanical properties. Mullite grains in composites formeda nearly continuous phase in which zirconia grains were distributed yielding better mechanical and fracture properties.
