| Abstract: | 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. |
