【摘要】 纳米In2O3粉末是一种用途广泛的多功能材料。以金属铟为原料,采用化学共沉淀法制得了氢氧化铟沉淀物。经过干燥,并且在不同温度下煅烧,可以制得纳米In2O3粉末。运用差热分析(DTA)、X射线衍射(XRD)、透射电镜(TEM)、电阻测试等观测手段对粉末进行了表征。比较系统地研究了热处理温度对粉末性能的影响,得出最适宜的热处理温度为700°C。更多还原

【Abstract】 Nano-sized In₂O₃ powder is a widely used multifunctional material.Metal indium was first dissolved in HCl;the solution was then neutralized by ammonia;In（OH）₃ precipitate was the final product of neutralization and precipitation.After drying and roasting at different temperatures nano-sized In₂O₃ powder was obtained.The powder was characterized by differential thermogravimetric analysis（DTA）,X-ray diffraction（XRD）,transmission electron microscopy（TEM） and resistant testing.The most feasible temperature was 700（°C）.更多还原
