Abstract
The dependences of the change in the microhardness, strength and density of the composite in the Al2O3‒ZrO2 system depending on the content of MgO‒SiO2 and SiO2‒ TiO2 additives were studied. Composite ceramics samples were obtained by semi-dry pressing with subsequent firing at 1400‒1550 °C. It was found that with a content of 5 % sintering additive and a firing temperature of 1550 °C, the microhardness and strength of the Al2O3‒ZrO2 composite ceramics with the addition of MgO‒SiO2 are higher than those of the composite with the addition of SiO2‒TiO2.
