Fabrication of Reticulated Porous Ceramics with Controlled Structure by Centrifuging Process


Article Preview

Reticulated porous ceramics (RPCs) with uniform structure were fabricated by a two-step centrifuging process. The two-step centrifuging process includes two centrifuging steps. In the first stage, the polyurethane sponges are coated with thin slurry through high speed centrifuging process. In the second stage, the as-prepared dried green body was recoated with thixotropic slurry through centrifuging process with an appropriate centrifuging speed. According to the results, the RPCs with controlled structure can be fabricated by modulating the rotation speed in the second centrifuging process.
