摘要
利用溶胶凝胶法制取纳米铟锡氧化物(ITO)粉末,研究了两种不同的分散剂对粉末粒度、团聚的影响,并用差热分析(DTA)、X-射线衍射(XRD)、扫描电镜(SEM)分析了所制得粉末的形貌。结果表明:两种分散剂均有减少纳米粉末团聚程度的效果,二号分散剂效果优于一号分散剂,而添加一号分散剂所制备的ITO纳米粉末的晶粒度比添加二号分散剂的细小;二者都对纳米粉末的形貌影响不大。
Nano-ITO powder is prepared with sol-gel process.Study is made on the effects of different dispersants on powder agglomeration.The structure and morphology of powders are analyzed through differential thermal analysis(DTA),X-ray diffractometer(XRD),scan electron microscope(SEM).The result shows that the two dispersants have obvious effects on reduction of agglomeration of ITO powder,No.2 dispersant is better than No.1,but the grain size of powder with No.2 dispersant is smaller than that with No.1 dispersant, and both of them have little effect on the structures and morphology of the said product.
