The paper presents the results of the investigation of the transition metals oxides – cobalt and iron additives influence on the sintering and properties of the ceramic material based on ZrO 2 - Al 2 O 3 system with 10 wt.% Al 2 O 3 . It is shown that the addition of the oxides resulted in the significant increase of the sintered ceramic materials ZrO 2 -10%Al 2 O 3 strength and decrease of sintering temperature. The maximum bending strength was more than 800 MPa (sintered at 1450 °C) and porosity was less than 1%.
