摘　　要：以金属铟锭与氧化锡粉末为原料,将铟锭与硝酸、氨水进行一系列反应生成氧化铟(ITO)粉末,并采用机械球磨法以氧化铟与氧化锡质量比为97:3的标准制备ITO粉体,研究了机械球磨中的氧化锆磨介直径、球磨速度与固含量对粉体形貌与性能的影响,通过X射线衍射仪(XRD)、扫描电镜(SEM)、四探针电阻仪、紫外-可见分光光度计、比表面积孔径分析仪、激光粒度分析仪以及手持X射线荧光光谱分析仪对粉体进行了表征。结果显示,随着固含量的增加,ITO粉体形貌由球形转变为棒性,但仍然为立方相结构;在固含量为30%,磨介直径为10 mm,球磨速度为120 r/min时可得到130 nm左右、导电性优异、可见光区域透过率高、紫外光区域吸收率高的亚微米级别粉体。Using metal indium ingot and tin oxide powder as raw materials,a series of reactions between indium ingot,nitric acid and ammonia water are used to produce indium oxide powder.The ITO powder is prepared by mechanical ball milling with a mass ratio of indium oxide to tin oxide of 97∶3.The paper studied the influence of zirconia grinding media diameter,ball milling speed and solid content in mechanical ball milling on the morphology and performance of the powder.X-ray diffractometer(XRD),scanning electron microscope(SEM),four-probe resistance meter,Ultraviolet-Visible spectrophotometer,specific surface area and aperture analyzer,laser particle size analyzer and handheld X-ray fluorescence spectrum analyzer were used to characterize the powder.The results showed that with the increase of solid content,the morphology of ITO powder changed from spherical to rod,but still with the cubic phase structure;130 nm can be obtained when the solid content is 30%,the grinding medium diameter is 10 mm,and the ball milling speed is 120 r/min It is a sub-micron powder with excellent conductivity,high transmittance in the visible light region,and high absorption rate in the ultraviolet light region.
