| Research Abstract |
We developed a chemical-free particle aggregation method using electrical field. DC and AC electrical field were applied to aqueous alumina suspensions and the effects of conditions of the applied electrical field on the aggregation behavior of the suspensions were investigated. It was shown that the DC electrical field can be useful for particle aggregation and the aggregates size increased with applied voltage and time, while AC electrical field showed no remarkable effect on the aggregation phenomenon. It was also found that decreasing the electrode distance should be effective to enhance the particle aggregation rather than increasing the applied voltage because too high voltage causes the increase in the suspension temperature and gas amount produced by electrolysis.
