Influence of Preparing Conditions on the Ytterbium-doped Tin Oxide Nano-powders

摘要:

以SnCl4•5H2O和Yb(NO3)3•6H2O为原料，氨水为沉淀剂，采用化学共沉淀法制备了镱掺杂二氧化锡纳米粉体，考察了反应温度、煅烧温度、分散剂的种类对所得纳米镱掺杂二氧化锡粉体的物相、晶粒度和形貌的影响。对粉体的前驱体进行综合热分析(TG-DTA)，用X射线衍射仪(XRD)、扫描电子显微镜(SEM)对产物的结构和形貌进行表征，得到共沉淀法制备纳米镱掺杂二氧化锡粉体的最佳条件：反应温度60 ℃，煅烧温度600 ℃，用非离子型PEG-600为分散剂。

Abstract:

Ytterbium-doped Tin Oxide Nano-powers were prepared by chemical co-precipitation method using SnCl4•5H2O and Yb(NO3)3•6H2O as precursors and NH3•H2O as precipitant. The effects of processing parameters on the particles were investigated. These parameters include reaction temperature, calcine temperature, kinds of dispersant. The Ytterbium-doped Tin Oxide precursors were studied by means of TG-DTA. The product particles were characterized by means of X-ray diffraction(XRD) and scanning electron microscopy(SEM). The optimized conditions for preparing nanometer Ytterbium-doped Tin Oxide powers were proposed:reaction temperature of 60 ℃, calcine temperature of 600 ℃, non-ionic dispersant of PEG-600.
