PREPARATION OF ULTRAFINE POWDER OF TiO_2 BY LASER IRRADIATION
激光加热气化法制备TiO_2超细粉

In this paper,a method preparing ultrafine TiO_2powder by laser irradiationwas presented.Meanwhile the formation conditions of particles were discussed.TEM ob-servation showed that the ultrafine powder was composed of particles from 6 to 20nm withanatase structure.Reseach results indicated that ultrafine TiO_2 particles could be obtainedby means of laser irradiation.
