Crystallization-stabilization mechanism of yttria-doped zirconia by hydrothermal treatment of mechanical mixtures of zirconia xerogel and crystalline yttria

摘要: Abstract Mechanical mixtures of zirconia xerogel and crystalline Y 2 O 3 were hydrothermally treated by microwave traditional route, respectively. Some used either as powders form or cylindrical compacts isostatically pressed at 150 MPa. The microwave–hydrothermal treatments performed 110, 150 200 °C for reaction times up to 2 h, whereas the hydrothermal 110 °C increasing 7 days. All in presence diluted (0.2 M) concentrated (2.0 M) solution (K CO +KOH) mineralizer. crystallization–stabilization mechanism synthesized Y-based full crystallization low temperature are discussed.
