The measurement and comparative analysis of the electrical and thermal conductivities and permeability of sintered nickel

The electrical conductivity (σ), the thermal conductivity (λ) and the permeability (μ) are given as functions of the volume fractions for a series of sintered nickel samples. It is shown that σ, λ and μ data can all be fitted to a single equation with the same two morphology parameters ƒc (a critical volume fraction) and t (an exponent) and separate bulk values for σNi, λNi and μNi.
