共沉淀法制备掺钕钇铝石榴石透明陶瓷:滴加方式的影响
Fabrication of neodymium-doped yttrium aluminium garnet transparent ceramics by co-precipitation: The effect of titration precipitation method
摘要
Abstract
Neodymium-doped yttrium aluminium garnet (Nd:YAG) powders were synthesized by co-precipitation with forward-titration and reverse-titration, respectively. The phase composition,morphology, particle size distribution of the powders were determined. The powder obtained by forward-titration was of major-phase YAG and a trace amount of YAM with a grain size about 24.7 nm, while the powder by reverse-titration was of pure-phase YAG with a grain size 26.6 nm. The average particle sizes of these powders were 1.26 μm and 1.86 μm respectively. The former was well dispersed with a narrow size distribution. Nd:YAG transparent ceramic was sintered at 1800 ℃ in vacuum. A few pores were observed in the forward-titration sample as compared with a few big holes and more pores at the grain boundaries of the reverse-titration sample. The transmission of the polished samples with thickness of lmm were 72% and 42% at 1064 nm, 65% and 35% at 400 nm respectively.关键词
