| Popis: | The effect of complex additives based on cobalt, iron, and manganese oxides and sodium silicate on the phase composition, microstructure, mechanical properties, and sintering of tetragonal zirconia ceramics stabilized with 3 mol % yttria and containing 10 wt % alumina (3Y–TZP–10Al2O3) was studied. The introduction of complex additives significantly affected sintering of the ceramics: the open porosity was less than 1% after annealing at 1250°C. The use of Na2Si2O5–0.33% Mn as a sintering additive provided the minimum of porosity for sintering temperature of 1300°C. Ceramics with flexural strength of 500 ± 16 MPa and the microhardness of 10 GPa was obtained. |
