中文摘要	Foaming and gelation of slurry is a recently invented processing route for fabricating porous ceramic. According to the method, a mechanical stir process was introduced to the ceramic slurry added with surfactant, then initiator was added to induce fast gelation between organic monomers and ceramic powder, the green body was obtained after a subsequently drying process. At last, porous ceramic was fabricated after sintering the green body at high temperature. Effects of surfactant volume content and several stirring factors on porosity are studied in this paper. It results that there is a proportional relationship between porosity and Reynolds number which only changes when stir time varies, different slurry or surfactant volume content results in similar relationship between porosity and Reynolds number.
