Abstract
The dependences of the formation of the microstructure and the phase composition of ceramics based on partially stabilized zirconium dioxide on the sintering temperature and the content of the sintering additive are established. It is shown that the introduction of an additive, which forms a low-temperature melt based on sodium silicate - Na2SiO3, leads to a decrease in the sintering temperature by 200 °C. As a result of the work, were obtained dense nanocrystalline materials with a crystal size of 100-200 nm, flexural strength up to 600 MPa and a sintering temperature of 1200-1250 °C.
