Sintering behaviour of zirconia and ceria-doped zirconia powders crystallized under hydrothermal conditions

International audienceUndoped and ceria doped zirconia fine particles, obtained under hydrothermal conditions, were heated from 200 degreesC to 1000 degreesC to investigate the monoclinic-tetragonal phase transformation. The nanosized powders exhibit suitable sinterability and reduced grain size in the sintered product. The ZrO2 doped with 12 mol% CeO2 was sintered to a single phase 100% tetragonal structure at 900 degreesC with a grain size of similar to 35 n
