Abstract
We have theoretically analyzed permeable powder materials with bidispe rse and biporous structures based on a conceptual approach using the c oncept of the matricity of porous systems. Approximate formulas are ob tained for the porosity, specific surface area, equivalent pore radius , monophase and interphase contact area. Using the percolation model, we estimate the matricity of powder materials and demonstrate the feas ibility of structural analysis of various powder systems using such an estimate.
