氧化锆是一种重要的催化荆及载体。

Zirconia is an important catalyst and support.

利用低温超强碱法制备出了纳米四方多晶氧化锆粉体。

The nanometer tetragonal polycrystal zirconia powder was prepared by the super alkaline method at low temperature.

使用络合沉淀法，控制温度、浓度、改变沉淀剂，制备了长短、粗细可控的棒状氧化锆。

The length and thickness can be controlled by altering the reaction temperatures and the reactant concentrations and the precipitant reagents.

由于生物陶瓷材料的弹性模量较小，很难采用添加氧化锆引起的相变增韧来解决上述缺点。

These disadvantages cannot be overcome by addition of tetragonal zirconia resulting in phase transition toughening, because of the low elastic module of the ceramic artificial bone materials.
