A continuously porous alumina sintered body was successfully fabricated using by the fibrous monolithic process, in which carbon and flour were used as a pore forming agent. An equation was driven for anticipating the microstructural change during extrusion as a function of the extrusion ratio, and it was identified that the resultant microstructure obtained from using the fibrous monolithic process agreed well with the calculated size using the equation. The third passed and sintered alumina body includes continuous pores of about 42.5 μm in diameter at an intended direction, while the second one consists of 228 μm. Fine pores were also found to form along the alumina surfaces with 0.1-10 μm in diameter. There was no shape change during binder burning out and sintering processes.
