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.
