The formation of self-reinforced composites in the ZrO2–Y2O3–CeO2–Al2O3 system is investigated. Depending on different sintering conditions, plates of CeAlO3, T-ZrO2, and α-Al2O3 are formed in the matrix based on a solid solution of ZrO2. The self-reinforced composite with fracture toughness 17–20 MPa ⋅ m0.5 is obtained in optimum sintering conditions. In this composite, α-Al2O3 plates as well as individual Ce2O3 ⋅ 11Al2O3 plates are arranged in the matrix based on T-ZrO2. Selfreinforced composites in the ZrO2–Y2O3–CeO2–Al2O3 system have a considerable potential for various engineering ceramic materials with tailored combinations of properties, e.g., for medical applications (surgical tools and bioinert implants).
