To enhance filtration performance of foam ceramics, effects of electric field on filtration performance of foam ceramics were studied. Results show that external electric field can change the wettability between melt and foam ceramics and can improve filtration performance of foam ceramics. Meanwhile, chemical composition of melt is not affected by external electric field.
