摘　　要：本文提出一种高效回收SnO2陶瓷电极的技术,采用磁控气化回收的方法将SnO2电极制成复合纳米粉末,实现废电极的回收再利用。借助BET(比表面积)、XRD(X射线衍射)和SEM(扫描电子显微镜)等技术对粉末进行表征,结果表明,所回收制备的SnO2复合粉末颗粒形貌呈类球形,平均粒径dBET在100 nm左右。XRD结果表明,未经热处理的粉末晶粒结构为四方金红石型SnO2结构,其中存在极少量SnO,经900℃热处理后,只存在单一四方金红石型SnO2结构。An efficient method of recycling SnO2 ceramic electrode was presented in this paper.By gasification technology,SnO2 ceramic electrode changed into nanopowders immediately.The powders obtained were characterized by means of XRD and SEM.The results show that the SnO2 compound powders prepared by gasification were quasi-spherical,average particle size dBET was about 100 nm.The XRD data indicates that a little SnO was found besides SnO2 for the powder untreatment and for the powder treated at 900 ℃,the crystal lattice was single SnO2 cubic rutile configuration.
