A study on preparation of tetragonal zirconia polycrystals (TZP) in the TiO2-Y2O3-ZrO2 system

Hydrothermal techniques were used to prepare micropowders within the TiO2-Y2O3-ZrO2 system. Phase compositions and particle sizes of the powders were determined. Monoclinic and tetragonal zirconia were the major phases. In compositions with high TiO2 concentrations, ZrTiO4 was found. Both TiO2 and Y...

Beschreibung
Zusammenfassung:	Hydrothermal techniques were used to prepare micropowders within the TiO2-Y2O3-ZrO2 system. Phase compositions and particle sizes of the powders were determined. Monoclinic and tetragonal zirconia were the major phases. In compositions with high TiO2 concentrations, ZrTiO4 was found. Both TiO2 and Y2O3 affect crystallite sizes of the powders. The fracture toughness of the samples sintered at 1300 C was measured. The TZP bodies show good mechanical properties. 22 refs.
