Abstract

Ceramic materials based on [97Zr3Yb]O2 nanopowder are obtained using the hydrolysis sol-gel method. The phase composition of the base material and that modified by aluminum, yttrium, and neodymium cations is represented by solid solutions based on ZrO2 in the tetragonal system. The ceramic materials exhibit high strength that grows with increasing the modifier content. It is established that barothermal treatment reduces the porosity in ceramic materials and increases microhardness, strength, and elastic moduli, as well as the translucency coefficient. The new materials are promising as structural materials for engineering and medicine.
