Abstract
The structure and micromechanical properties of granulated zirconia ceramics synthesized from suspensions with various Y-ZrO2 concentrations have been studied. It is established that an increase in the Y-ZrO2 content up to 25% eliminates the cracking of granules during heat treatment and improves their micromechanical characteristics. It is shown that elevated nanohardness of the synthesized granules is related to an increase in the content of tetragonal t-ZrO2 phase.
