Purpose: This study deals with the effects of colemanite (Ca2B6O115H2O) on properties of slip-cast mullite–zirconia composites prepared via reaction–sintering of kaolinite, alumina and zircon powders. Design/methodology/approach: Colloidal processing (slip casting) is the route towards preparing these materials using 45 vol.% aqueous suspensions of a mixture of fine powders stabilized with polyacrylate solution as a dispersant. Findings: The influence of powder composition on physical, mineralogical properties, and microstructure of these composites after firing at 1450, 1500 and 1550°C are observed. The results show that the density of composites tends to increase with the addition of 7 wt.% colemanite. XRD analyses reveal that using colemanite during the synthesis of mullite-zirconia composites lowers the reaction temperature. All of the composites consist of irregularly shaped mullite and round-shaped zirconia grains, which are distributed homogenously. Practical implications: Mullite–zirconia composites, owing to their chemical inertness and good resistance against chemical attack-corrosion by siliceous and metallic melts, they are employed in the glass industry. Originality/value: Reaction sintering process is considered as a promising technology for preparing mullite-zirconia composites, because it has some advantages such as low cost of traditional raw materials, straightforward production technology and low manufacturing cost.
