Quantitative Analysis of Permeable Ceramic Structure Made From Narrow-Fraction Electrocorundum Powder and Corundum Hollow Microspheres

The structure of permeable ceramic made from narrow-fraction electrocorundum grade F 240 and corundum hollow microspheres is studied using computer analysis of images obtained in a scanning electron microscope. Such quantitative indices are determined as pore shape, pore shape distribution, pore twisting factor, etc. It is shown that pore shape has a decisive effect on specimen permeability.
