摘要

采用湿化学共沉淀法合成了Nd3+掺杂的氧化镥纳米晶粉体, 研究了三种不同沉淀剂(NH4OH、NH4HCO3、NH4OH+NH4HCO3)对Nd3+∶Lu2O3纳米晶粉体性能的影响. 采用NH4OH+NH4HCO3混合溶液作复合沉淀剂所得粉体具有比表面积高(13.37m2/g)、颗粒尺寸小(~30nm)、粒度分布窄(60~160nm)的优点. 该粉体经过干压和等静压成型后, 素坯从室温至1400℃获得的线性收缩率可达17%, 其烧结活性明显高于其它两种沉淀剂所得的粉体. 在流动H2气氛下, 经1880℃/8h烧结可获得具有优良光学透明性的Nd3+∶Lu2O3透明陶瓷, 在1080nm波长处的直线透过率超过75%.

Abstract

Neodymium doped lutetia nanocrystalline powders were synthesized by a wet chemical processing using three different precipitants, i.e. ammonium hydroxide (NH4OH), ammonium hydrogen carbonate (NH4HCO3) and the mixed solution of NH4OH+NH4HCO3, respectively. Compared with the other two precipitants, the Nd-doped Lu2O3 powder synthesized by mixed solution of NH4OH+NH4HCO3 had the advantages of higher specific surface area, smaller particle size (30nm) and narrower particle size distribution (from 60nm to 160nm). Green compacts were formed from as-synthesized Nd3+∶Lu2O3 powders by dry-pressing followed by a cold isostatic pressing. The green compact made from powders synthesized by mixed precipitants acheived the highest linear thermal shrinkage of about 17% at 1400℃, demonstrating more superior sinterbility than the other two powders. Highly transparent samples were obtained after being sintered in flowing H2 atmosphere at 1880℃ for 8h. The linear optical transmittance of the polished transparent samples reached 75.5% at the wavelength of 1080nm.

Key words： Nd3+∶Lu2O3; co-precipitation processing; powder characteristics; transparent ceramic
