The preparation and mechanical properties of composites 20 & # 37; molar fraction of Al 2 O 3 and 80 & # 37; [3Yb & # 8211; TZP] modified with strontium oxide. It is shown that in the process of heat treatment of the initial nanopowders, the strontium hexaaluminate phase is formed in situ. A correlation has been established between an increase in the concentration of the modifier and an increase in the volume fraction of the strontium hexaaluminate phase. It was revealed that the content of the modifier is higher than 3 & # 37; leads to an increase in the porosity of the composites. Determined that composites modified 1 & # 8211; 2 & # 37; molar fraction of SrO, have a flexural strength of 850 MPa, fracture toughness K 1c up to 11.3 MPa
