Abstract

In this paper,Ti∶Al2O3 nano-powders were prepared by the co-precipitation method for the first time.The nano-powders were characterized by TG/DTA,FTIR,XRD,TEM and EDS techniques.The results indicate that the pure α-Al2O3 phase can be obtained when the precursors were calcined at 1 200 ℃ for 1 h.The powders were 25~50 nm in size with well dispersed and narrow distributed spherical morphology.
