Abstract:
A new equation for calculating the electrical conductivity of sintered powder compacts is proposed. In this equation, the effective resistivity of porous compacts is a function of the fully dense material conductivity, the porosity of the compact and the tap porosity of the starting powder. The new equation is applicable to powder sintered compacts from zero porosity to tap porosity. A connection between this equation and the percolation conduction theory is stated. The proposed equation has been experimentally validated with sintered compacts of six different metallic powders. Results confirm very good agreement with theoretical predictions.read more

Thermal Conductivity: VIII, A Theory of Thermal Conductivity of Porous Materials
TL;DR: In this article, the effective thermal conductivity of a porous material is due to both conduction and radiation processes, and a theory is presented relating the effective conductivity to the conductivities of the solid material, to the emissivity of the surface of the pores, and to the size, shape, and distribution of the porous material.
