The relationship between particle size distribution and stacking density of powder for the prefabricated porous ceramic was derived from the model and the largest stacking density can be obtained as particle grading parameter δ is 4. The different porous ceramics made of different median particle diameter D50 and δ were prepared and the physical and chemical properties were carried out. The test result was compared with the theoretical model. The results show that the pore structure, particles bonding and physical and chemical properties are optimum for the porous ceramic made by particle grading 4.2, which matches the theoretical result.
