Estimation of the Parameters of the Porous Structure and Permeability of Monofraction Ceramics

  • Published:
Refractories and Industrial Ceramics Aims and scope

A method for assessing the structure parameters of porous ceramic materials by porosity and particle size is presented. Based on it, a physically more rigorous than the well-known Cozeny formula is obtained, a formula for determining the average (hydraulic) radius of the capillaries of permeable materials. The presented results of the calculation of the average radius of the capillaries of porous ceramics based on electrocorundum according to the obtained formula are in better agreement with experimental data than the calculations by the Cozeny formula.
