摘要
用微乳液法制备了经十二烷基苯磺酸钠（ＤＢＳ）和硬脂酸（ＳＴ）表面修饰的Ｃｒ２Ｏ３超微粒子。讨论了影响超微粒子粒度和萃取率的因素，并用ＴＥＭ，ＩＲ，ＴＧ，ＤＴＡ，ＸＲＤ，ＸＰＳ及紫外吸收光谱进行了表征。
This paper report the preparation of Cr2O3 ultrafine particles (UFP),thesurfaces of which were modified by sodium dodecyl benzene sulfonate(DBS) and stearic acid(ST). The most favourable experiment conditions for the preparation of Cr2O3 UFPwere studied. XRD,TEM,TG,DTA and XPS examinations were used to characterize thesamples.
