Abstract The microstructural and phase evolution, which leads to final zirconia-mullite tough ceramic composites by using reaction sintering of zircon-alumina mixtures with MgO and CaO as additives, has been investigated by electron microscopy and microanalysis. The results confirm that the reaction, in a first stage, produces zirconia inside an amorphous matrix as well as saphirine and spinel for MgO and anorthite for CaO additions respectively. Finally the glassy phase distribution, the mechanical behaviour and the microstructure of the final reaction sintered compacts are comparatively discussed.
