摘要

The paper studies the structure, phase composition, and mechanical properties of ceramics based on zirconium dioxide (ZrO2), depending on the content of yttrium oxide (Y2O3) in the solid solution. It is found that the increased Y2O3 content in initial powders from 3 to 5 mol%, leads to the higher content of the cubic ZrO2 phase in the sintered material and the higher average grain size and transmittance, but lower strength. It is shown that nanomaterials based on the ZrO2–Y2O3 system can be used for dental restoration with high aesthetic properties.
