Predicting the conductivity of biporous powder materials

The electrical conductivity of biporous permeable powdered materials is calculated on the basis of percolation theory. These materials are made with a pore-forming additive having a different ratio of particle size than does the metal phase. Calculations for nickel powder specimens as an example are...

Zusammenfassung:The electrical conductivity of biporous permeable powdered materials is calculated on the basis of percolation theory. These materials are made with a pore-forming additive having a different ratio of particle size than does the metal phase. Calculations for nickel powder specimens as an example are in satisfactory agreement with the experimental data.
