Abstract

Yttria-stabilised zirconia powders and thick films with nanocrystalline structure have been obtained using an original hydrothermal route allowing the crystallisation at low temperatures. The microstructure evolution has been revealed using TDA and TG, RX diffraction and SEM. The mechanism of powder and film formation is proposed
