摘要:
   研究了直接沉淀法合成Sc2O3纳米粉的工艺。以硝酸钪[Sc(NO3)3]为母盐,氨水(NH3·H2O)作沉淀剂,采用直接沉淀法合成出网状的前躯沉淀物,同时分析了前驱体的热分解过程。通过X射线衍射和红外光谱对前躯体的物相组成进行了定性分析,结果表明,该前躯沉淀物为γ〖JP2〗ScOOH·nH2O与NH4Sc3(SO4)2(OH)6nH2O的两相混合物。前躯体经过微化处理后,在1 000 ℃的温度下煅烧,生成的Sc2O3纳米粉具有纯度较高、颗粒粒度小(40 nm)、粒度分布窄、近似球形Sc2O3的性能,但是粉体产生了轻微团聚的现象。
Abstract:
Synthesis of Sc2O3 nanopowders by direct precipitation approach has been investigated. The netlike precursor was synthesized taking ammonia as precipitant and scandium nitrate solution as mother liquor. Phase transformation of the precursor upon calcination was analyzed. The results show that Sc2O3 nanopowders calcined at 1 000 ℃ are spherical, ultrafine (40 nm), and of high purity and narrow particle size distribution.
