Abstract:Symmetrical alternating current (SAC) was applied during yttria precursor nano-powder precipitation. The effects of SAC on the morphology and grain size of the yttria precursor were investigated via scanning electron microscopy (SEM) and X-ray diffraction (XRD). It was found the precursor to be transformed from irregular platelets/spheres to uniform spheres due to the SAC vibration effect. High frequency and density of SAC exerted greater influence on the morphology and grain size of the yttria precursor than weaker one.
Keywords:Symmetrical alternating current  Yttria precursor  Grain size  Dielectrophoresis
