摘要: 以氧氯化锆为前驱物, 用沉淀法制得了纳米氧化锆(ZrO2)粒子, 并探讨了沉淀过程中沉淀剂加入速度、洗涤和干燥方式对ZrO2晶粒尺寸和晶型转变的影响。结果表明,合成过程中干燥方式对ZrO2样品的尺寸影响最大。沉淀剂的加入速度越快,越有利于四方晶相ZrO2的稳定,在制备过程中采用醇洗、真空干燥的方式比水洗、空气干燥更有利于抑制ZrO2从四方相到单斜相的相变。

Abstract: ZrO2 nanoparticle was prepared by precipitation method using ZrOCl2 as precursor. The influences of the adding rate of precipitation agent, washing and drying method on the particle size and crystalline phase of ZrO2 nanoparticles were studied. It is found that the transformation from tetragonal to monoclinic is delayed when Zr(OH)4 was washed by ethanol. When NH3·H2O was added rapidly and ZrO2 was dried by vacuum, the phase transformation of ZrO2 is inhibited obviously.
