Abstract

The synthesis technology of a chemically pure nanodisperse precursor powder (10–12 nm) based on a tetragonal solid zirconia (t-ZrO2) solution in the ZrO2 system (Y2O3)–Al2O3 for restorative dentistry is developed. A ceramic material with a crystallite size of 60–65 nm is obtained; its phase composition, dispersion, microstructure, and physical and mechanical properties are investigated; and its low-temperature moisture aging structural stability is established.
