Synthesis and Characterization of Ti∶Al2O3 Nano-Powders by Co-Precipitation Method |
|
摘要: 本文采用共沉淀法合成了Ti∶Al2O3纳米粉体。利用热重/差热(TG/DTA)/X射线衍射(XRD)/红外光谱(FTIR)/扫描电镜(SEM)以及能谱 (EDS)等分析方法对合成的Ti∶Al2O3纳米粉体进行了表征。结果分析表明:前驱体在1 200 ℃下,保温1 h可以得到纯的α-Al2O3晶相;粉体的粒径均匀、分散性好,平均粒径在25~50 nm之间。 |

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. |
