摘要
以SnCl4.5H2O、氨水和HF酸为主要原料,用化学方法制取了掺氟氧化锡(FTO)纳米粉末。用XRD、SEM分别研究了FTO粉末的相结构和形貌,用比表面仪测定了粉末比表面积,同时测试了FTO粉末的电阻率。结果表明:FTO粉末是四方晶系金红石结构;在500℃下焙烧制取的粉末电阻率最低,为50?.m,比表面积为61.00m2/g。采用无水酒精球磨分散等步骤,可有效防止粉末团聚。
Fluorine-doped tin oxide（SnO2：F,FTO） nano-powder was prepared by chemical method.The phase composition and the morphology of FTO powder were studied with XRD and SEM.The specific surface area and the resistivity of FTO powder were measured.The results show that the prepared FTO powder possesses tetragonal system rutile structure.The FTO powder calcined at 500 ℃ has the lowest resistivity of 50 ？.m and the specific surface area of 61.00 m2/g.The nano-powder agglomeration can be retarded by ball mill dispersing with anhydrous alcohol step,etc.
