摘要: 以碳酸氢铵或氨水为沉淀剂,采用化学共沉淀法制备Yb:YAG透明陶瓷纳米粉体,利用扫描电镜、X射线衍射对粉体的形貌和物相结构进行表征。研究表明:以碳酸氢铵为沉淀剂制备的前驱体在1 200 ℃煅烧后可制得无杂质的YAG(Y3Al5O12)粉体,以氨水为沉淀剂制备的前驱体在1 200 ℃煅烧后制得的YAG粉体中有杂质相YAM(Y4Al2O9);以碳酸氢铵为沉淀剂制备的YAG粉体的分散性好,碳酸氢铵溶液与母盐溶液中铝离子浓度最佳配比为10∶1,粉体粒度在100~250 nm。

Abstract: Yb:YAG transparent ceramic nano-powder was prepared by chemical co-precipitation method,with ammonium bicarbonate or ammonia as the precipitant.The morphology and phase structure of Yb:YAG nano-powder were characterized by scanning electron microscopy(SEM) and X-ray diffraction(XRD).Results showed that pure YAG phase nano-powder was obtained by calcining the precursors prepared by using ammonium bicarbonate as the precipitant at 1 200 ℃.However,YAM(Y4Al2O9) phase was found in the XRD patterns of the Yb:YAG powders synthesized by co-precipitation method using ammonia as precipitant at 1 200 ℃.Well dispersive,pure YAG nano-powders with the particle size in the range of 100~250 nm were obtained by calcining the precursor prepared by using ammonium bicarbonate as the precipitant and the optimum concentration ratio of NH4HCO3 to Al3+ was 10∶1.

Key words: Yb:YAG, co-precipitation, precipitant, nanometer powders
