摘要
研究了利用水热技术合成TiO2-Y2O3-ZrO2系统微粉。实验测定了粉料的相组成和晶粒尺寸,单斜和四方ZrO2是主要晶相。在含高TiO2的结构中,发现了ZrTiO4。测量了在1300℃烧结样品的断裂韧性。这类四方氧化锆晶体显示出了良好的机械性质。
Hydrothermal techniques were used to prepare micropowders within the TiO2-Y2O3-ZrO2 system. Phase compositions and particle size of the powders were eater mined. Monoclinic and tetragonal zirconia were the major phases. In compositions with high TiO2 concentrations; ZrTiO4 was found. The fracture toughness of the samples sintered at 1300℃ was measured. The TZP bodies show good mechanical properties.
