Gasification Technology of Recycling SnO₂ Ceramic Electrode

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.
