The fracture strength properties of porous ceramics were examined by 3-points bending tests and rotary bending fatigue tests. The 3-points bending strengths of porous ceramics depended on effective volumes of specimen and the fracture was similar to that of Al_2O_3. Also, the rotary bending fatigue strengths of the porous ceramics didn't decrease at (10)^3∿(10)^7 cycles.
