Heading: Science for ceramic production

The preparation of composites based on nanopowders synthesized by the sol-gel method in the system of aluminum oxide and tetragonal zirconium dioxide stabilized by cerium cations (Al 2 O 3 - [Ce-TZP]) is described. ... It is shown that the modification of the compositions with calcium oxide promotes the formation of a dispersion-strengthening phase in the form of long-prismatic grains during the sintering of composites. The presence of this phase affects the increase in strength and resistance to brittle fracture of composites with both the ZrO 2 matrix and the Al 2 O 3 matrix. The static bending strength of composites reaches 1000 MPa, and the fracture toughness K 1s increases to 11.0 MPa m 1/2
