Study of Permeable Ceramic Pore Structure by X-Ray Microtomography

Results are given for a study of the pore structure of permeable ceramic made from nature-fraction electrocorundum grade Alodur F420 with different particle shape by computer microtomography. Cellular models are built for ceramic specimen pore space. Pore volume and radius distribution and also the length and diameter of channels with respect to size are calculated. On the basis of numerical values obtained for pores and channels the difference in permeability of specimens made from electrocorundum with differently shaped crystal is explained.
