In this study, the fabrication of alumina-based composites (in situ) in the Al-ZrO2(ZrSiO4)-B2O3(TiO2)-C system was carried out by the self-combustion synthesis method. According to the results, different compounds of zirconium aluminide, diboride, and disilicide, boron, zirconium and silicon carbide, and aluminum titanate were formed in the alumina matrix, depending on the type of system. For samples sintered by spark plasma sintering in the Al-ZrSiO4-B2O3-C system, which exhibited the highest relative density (92%) and a more homogeneous microstructure than the other systems, the highest mechanical properties (Vickers hardness of 1159, flexural strength of 271.5 MPa, and fracture toughness of 8.76 MPa·m1/2) were obtained.
