Sonication was carried out through the curing process of furan resin by using an ultrasonic homogenizer at thefrequency of 20 kHz and the intensity of 50 W/cm2. Carbonaceous fine particles were added to furan resin to investigate the sedimentation behavior in cured resin. Curing rate of furan resin was accelerated by sonication, which was effectiveto remove out the included larger pores and also to avoid the sedimentation of the particles. The additives weredispersed uniformly in the cured furan resin by sonication. Therefore, it was clarified that the additives were able tobe distributed homogeneously in the furan resin by the ultrasonic treatment.
