Abstract
ABSTRACTThe effect of electric current pulse (ECP) on preparing nano Y2O3 powder was initially investigated in this paper. From the determination of thermogravimetric analysis, differential scanning calorimetry and X-ray diffraction, it was revealed that the composition of non-calcined precursor had changed due to the application of ECP. In addition, the scanning electron microscope results indicated that Y2O3 powders fabricated by ECP treatment had less aggregate and were in nano size. Therefore, the ECP treatment is a promising way to prepare nano Y2O3 powder.This paper is part of a themed issue on Materials in External Fields.
